1-90 6.19e-57

conserved catalytic core domain of RNA-dependent RNA polymerase (RdRp) from the positive-sense single-stranded RNA [(+)ssRNA] viruses and closely related viruses; This family contains the catalytic core domain of RdRp of RNA viruses which belong to Group IV of the Baltimore classification system, and are a group of related viruses that have positive-sense (+), single-stranded (ss) genomes made of ribonucleic acid (RNA). RdRp (also known as RNA replicase) catalyzes the replication of RNA from an RNA template; specifically, it catalyzes the synthesis of the RNA strand complementary to a given RNA template. The Baltimore Classification is divided into 7 classes, 3 of which include RNA viruses: Group IV (+) RNA viruses, Group III double-stranded (ds) RNA viruses, and Group V negative-sense (-) RNA viruses. Baltimore groups of viruses differ with respect to the nature of their genome (i.e., the nucleic acid form that is packaged into virions) and correspond to distinct strategies of genome replication and expression. (+) viral RNA is similar to mRNA and thus can be immediately translated by the host cell. (+)ssRNA viruses can also produce (+) copies of the genome from (-) strands of an intermediate dsRNA genome. This acts as both a transcription and a replication process since the replicated RNA is also mRNA. RdRps belong to the expansive class of polymerases containing so-called palm catalytic domains along with the accessory fingers and thumb domains. All RdRps also have six conserved structural motifs (A-F), located in its majority in the palm subdomain (A-E motifs) and the F motif is located on the finger subdomain. All these motifs have been shown to be implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. In addition to Group IV viruses, this model also includes Picobirnaviruses (PBVs), members of the family Picobirnaviridae of dsRNA viruses (Baltimore classification Group III), which are bi-segmented dsRNA viruses. The phylogenetic tree of the RdRps of RNA viruses (realm Riboviria) showed that picobirnaviruses are embedded in the branch of diverse (+)RNA viruses; sometimes they are collectively referred to as the picornavirus supergroup. RdRps of members of the family Permutatetraviridae, a distinct group of RNA viruses that encompass a circular permutation within the RdRp palm domain, are not included in this model.

1-114 2.91e-19

RNA_dep_RNAP: RNA-dependent RNA polymerase (RdRp) is an essential protein encoded in the genomes of all RNA containing viruses with no DNA stage. RdRp catalyzes synthesis of the RNA strand complementary to a given RNA template. RdRps of many viruses are products of processing of polyproteins. Some RdRps consist of one polypeptide chain, and others are complexes of several subunits. The domain organization and the 3D structure of the catalytic center of a wide range of RdRps, including those with a low overall sequence homology, are conserved. The catalytic center is formed by several motifs containing a number of conserved amino acid residues. This subfamily represents the RNA-dependent RNA polymerases from all positive-strand RNA eukaryotic viruses with no DNA stage.

1-154 5.65e-14

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the order Picornavirales of positive-sense single-stranded RNA [(+)ssRNA] viruses; This family contains the catalytic core domain of RdRp of Picornavirales, an order of (+)ssRNA viruses. The order Picornavirales comprises viruses that historically are referred to as picorna-like viruses and which are classified into eight virus families: Caliciviridae, Dicistroviridae, Iflaviridae, Marnaviridae, Picornaviridae, Polycipiviridae, Secoviridae, and Solinviviridae. All known genomes of Picornavirales members encode proteins with helicase, 3C-like protease, and RdRp domains, as well as capsid proteins with related structures, although the genome organizations can differ among viruses. The picornavirus genome is replicated via a negative-sense (-) RNA intermediate by the viral RdRp, named 3Dpol, which uses VPg (the product of 3B) as a primer to initiate the replication process. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.

2-134 3.82e-04

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Marnaviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses, in the order Picornavirales; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Marnaviridae, order Picornavirales. Member viruses have a (+)ssRNA genome. They are mono- or dicistronic, have a polyadenylate tail and have conserved motifs for RNA helicase, RdRp, and structural protein domains. The first RNA virus isolated and characterized that infects a marine protist was Heterosigma akashiwo RNA virus (HaRNAV) in the genus Marnavirus, that infects the toxic bloom-forming Raphidophyte alga, Heterosigma akashiwo. Recently, it has undergone a major taxonomic revision and now includes 20 species within 7 genera, which include Bacillarnavirus, Kusarnavirus, Labyrnavirus, Locarnavirus, Marnavirus, Salisharnavirus, and Sogarnavirus. RdRps catalyze RNA template-dependent formation of phosphodiester bonds between ribonucleotides in the presence of divalent metal ions. The initiation of synthesis occurs at the 3'-end of the template in a VPg-dependent manner, and proceeds in the direction of 5'-3'. The active sites of RdRps are highly conserved in different species of picornaviruses. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.

Many flaviviruses are host-specific and pathogenic, such as hepatitis C virus in the genus Hepacivirus. The majority of known members in the genus Flavivirus are arthropod borne, and many are important human and veterinary pathogens (e.g., yellow fever virus, dengue virus). Virions are typically spherical in shape with a lipid envelope. Virions have a single, small, basic capsid (C) protein and two (genera Flavivirus, Hepacivirus and Pegivirus) or three (genus Pestivirus) envelope proteins. They contain a single, long ORF flanked by 5'- and 3'-terminal non-coding regions, which form specific secondary structures required for genome replication and translation. Translational initiation of genomic RNA is cap dependent in the case of members of the genus Flavivirus. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Picornaviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Picornaviridae, order Picornavirales. The Picornaviridae family consists of small, icosahedral viruses with (+)ssRNA genomes. Characteristic features of all members of the family Picornaviridae are three capsid proteins with beta-barrel folding, polyprotein processing by virus-encoded cysteine proteinase(s), and replication by an RdRp with a YGDD sequence motif. The family Picornaviridae comprises 68 genera containing 158 species, but many viruses are presently awaiting classification. The established genera of the family include: Aphthovirus, Avisivirus, Crohivirus, Enterovirus, Teschovirus, Cardiovirus, Erbovirus, Kobuvirus, Hepatovirus, Parechovirus, Aquamavirus, Avihepatovirus, Avisivirus, Cosavirus, Dicipivirus, Fipivirus, Gallivirus, Hunnivirus, Kunsagivirus, Limnipivirus, Megrivirus, Mischivirus, Mosavirus, Oscivirus, Pasivirus, Passerivirus, Rabovirus, Rosavirus, Sakobuvirus, Salivirus, Sapelovirus, Senecavirus, Sicinivirus, and Tremovirus. The Picornaviridae contains many important human and animal pathogens including enteroviruses (such as poliovirus, enterovirus, coxsackievirus, and rhinovirus), cardioviruses (such as encephalomyocarditis virus and Theiler's virus), hepatitis A virus and foot-and-mouth disease virus. Infection with various picornaviruses may cause encephalitis, febrile rash illnesses (hand-foot-and-mouth disease), aseptic meningitis, hepatitis, conjunctivitis, herpangina, myositis and myocarditis, and the common cold. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Caliciviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Caliciviridae, order Picornavirales. Member viruses have a viral (+)ssRNA genome, which is not segmented. The family Caliciviridae, includes eleven genera: seven genera of which infect mammals (Lagovirus, Norovirus, Nebovirus, Recovirus, Sapovirus, Valovirus, and Vesivirus), two genera of which infect birds (Bavovirus, Nacovirus), and two genera of which infect fish (Minovirus and Salovirus). Each genus includes 1-2 species. Human noroviruses are a leading cause of acute gastroenteritis in humans. Furthermore, unclassified caliciviruses have been detected in geese, yellowfin seabream, greater green snake, arctic lamprey, frogs and various Australian birds, highlighting the wide host range of viruses in the family Caliciviridae. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.
