ubiquitin-like modifier-activating enzyme ATG7 isoform X23 [Homo sapiens]

Protein Classification

ubiquitin-activating E1 family protein; sulfur carrier protein ThiS adenylyltransferase( domain architecture ID 10107282)

ubiquitin-activating E1 family protein is an activating enzyme similar to Osphranter rufus ubiquitin-activating enzyme E1 Y that activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding a ubiquitin-E1 thioester and free AMP; sulfur carrier protein ThiS adenylyltransferase (ThiF) catalyzes the adenylation of ThiS which is involved in the formation of 5-methyl-4-(beta-hydroxyethyl)thiazole phosphate

 46-371 0e+00

Apg7 is an E1-like protein, that activates two different ubiquitin-like proteins, Apg12 and Apg8, and assigns them to specific E2 enzymes, Apg10 and Apg3, respectively. This leads to the covalent conjugation of Apg8 with phosphatidylethanolamine, an important step in autophagy. Autophagy is a dynamic membrane phenomenon for bulk protein degradation in the lysosome/vacuole.

 1-384 6.46e-176

E1-like protein-activating enzyme Gsa7p/Apg7p; This model represents a family of eukaryotic proteins found in animals, plants, and yeasts, including Apg7p (YHR171W) from Saccharomyces cerevisiae and GSA7 from Pichia pastoris. Members are about 650 to 700 residues in length and include a central domain of about 150 residues shared with the ThiF/MoeB/HesA family of proteins. A low level of similarity to ubiquitin-activating enzyme E1 is described in a paper on peroxisome autophagy mediated by GSA7, and is the basis of the name ubiquitin activating enzyme E1-like protein. Members of the family appear to be involved in protein lipidation events analogous to ubiquitination and required for membrane fusion events during autophagy.

E1-like protein-activating enzyme Gsa7p/Apg7p; This model represents a family of eukaryotic proteins found in animals, plants, and yeasts, including Apg7p (YHR171W) from Saccharomyces cerevisiae and GSA7 from Pichia pastoris. Members are about 650 to 700 residues in length and include a central domain of about 150 residues shared with the ThiF/MoeB/HesA family of proteins. A low level of similarity to ubiquitin-activating enzyme E1 is described in a paper on peroxisome autophagy mediated by GSA7, and is the basis of the name ubiquitin activating enzyme E1-like protein. Members of the family appear to be involved in protein lipidation events analogous to ubiquitination and required for membrane fusion events during autophagy.

 46-201 1.48e-24

Superfamily of activating enzymes (E1) of the ubiquitin-like proteins. This family includes classical ubiquitin-activating enzymes E1, ubiquitin-like (ubl) activating enzymes and other mechanistic homologes, like MoeB, Thif1 and others. The common reaction mechanism catalyzed by MoeB, ThiF and the E1 enzymes begins with a nucleophilic attack of the C-terminal carboxylate of MoaD, ThiS and ubiquitin, respectively, on the alpha-phosphate of an ATP molecule bound at the active site of the activating enzymes, leading to the formation of a high-energy acyladenylate intermediate and subsequently to the formation of a thiocarboxylate at the C termini of MoaD and ThiS.

ThiF_MoeB_HesA. Family of E1-like enzymes involved in molybdopterin and thiamine biosynthesis family. The common reaction mechanism catalyzed by MoeB and ThiF, like other E1 enzymes, begins with a nucleophilic attack of the C-terminal carboxylate of MoaD and ThiS, respectively, on the alpha-phosphate of an ATP molecule bound at the active site of the activating enzymes, leading to the formation of a high-energy acyladenylate intermediate and subsequently to the formation of a thiocarboxylate at the C termini of MoaD and ThiS. MoeB, as the MPT synthase (MoaE/MoaD complex) sulfurase, is involved in the biosynthesis of the molybdenum cofactor, a derivative of the tricyclic pterin, molybdopterin (MPT). ThiF catalyzes the adenylation of ThiS, as part of the biosynthesis pathway of thiamin pyrophosphate (vitamin B1).

 46-170 1.59e-09

Ubiquitin activating enzyme (E1) subunit UBA2. UBA2 is part of the heterodimeric activating enzyme (E1), specific for the SUMO family of ubiquitin-like proteins (Ubls). E1 enzymes are part of a conjugation cascade to attach Ub or Ubls, covalently to substrate proteins consisting of activating (E1), conjugating (E2), and/or ligating (E3) enzymes. E1 activates ubiquitin by C-terminal adenylation, and subsequently forms a highly reactive thioester bond between its catalytic cysteine and Ubls C-terminus. The E1 also associates with E2 and promotes ubiquitin transfer to the E2's catalytic cysteine. Post-translational modification by SUMO family of ubiquitin-like proteins (Ublps) is involved in cell division, nuclear transport, the stress response and signal transduction. UBA2 contains both the nucleotide-binding motif involved in adenylation and the catalytic cysteine involved in the thioester intermediate and Ublp transfer to E2.

Ubiquitin activating enzyme (E1) subunit UBA3. UBA3 is part of the heterodimeric activating enzyme (E1), specific for the Rub family of ubiquitin-like proteins (Ubls). E1 enzymes are part of a conjugation cascade to attach Ub or Ubls, covalently to substrate proteins. consisting of activating (E1), conjugating (E2), and/or ligating (E3) enzymes. E1 activates ubiquitin(-like) by C-terminal adenylation, and subsequently forms a highly reactive thioester bond between its catalytic cysteine and Ubls C-terminus. E1 also associates with E2 and promotes ubiquitin transfer to the E2's catalytic cysteine. Post-translational modification by Rub family of ubiquitin-like proteins (Ublps) activates SCF ubiquitin ligases and is involved in cell cycle control, signaling and embryogenesis. UBA3 contains both the nucleotide-binding motif involved in adenylation and the catalytic cysteine involved in the thioester intermediate and Ublp transfer to E2.

E1_ThiF_like. Member of superfamily of activating enzymes (E1) of the ubiquitin-like proteins. The common reaction mechanism catalyzed by E1-like enzymes begins with a nucleophilic attack of the C-terminal carboxylate of the ubiquitin-like substrate, on the alpha-phosphate of an ATP molecule bound at the active site of the activating enzymes, leading to the formation of a high-energy acyladenylate intermediate and subsequently to the formation of a thiocarboxylate at the C termini of the substrate. The exact function of this family is unknown.

 46-118 6.24e-07

Ubiquitin activating enzyme (E1), repeat 2-like. E1, a highly conserved small protein present universally in eukaryotic cells, is part of cascade to attach ubiquitin (Ub) covalently to substrate proteins. This cascade consists of activating (E1), conjugating (E2), and/or ligating (E3) enzymes and then targets them for degradation by the 26S proteasome. E1 activates ubiquitin by C-terminal adenylation, and subsequently forms a highly reactive thioester bond between its catalytic cysteine and ubiquitin's C-terminus. E1 also associates with E2 and promotes ubiquitin transfer to the E2's catalytic cysteine. A set of novel molecules with a structural similarity to Ub, called Ub-like proteins (Ubls), have similar conjugation cascades. In contrast to ubiquitin-E1, which is a single-chain protein with a weakly conserved two-fold repeat, many of the Ubls-E1are a heterodimer where each subunit corresponds to one half of a single-chain E1. This CD represents the family homologous to the second repeat of Ub-E1.
