Six-transmembrane helical domain of the ATP-binding cassette transporters; This family represents a subunit of six transmembrane (TM) helices typically found in the ATP-binding cassette (ABC) transporters that function as exporters, which contain 6 TM helices per subunit (domain), or a total of 12 TM helices for the complete transporter. The ABC exporters are found in both prokaryotes and eukaryotes, where they mediate the cellular secretion of toxic compounds and a various type of lipids. In addition to ABC exporters, ABC transporters include two classes of ABC importers, classified depending on details of their architecture and mechanism. Only the ABC exporters are included in this family. ABC transporters typically consist of two transmembrane domains (TMDs) and two nucleotide-binding domains (NBDs). The sequences and structures of the TMDs are quite varied between the different type of transporters, suggesting chemical diversity of the translocated substrates, whereas NBDs are conserved among all ABC transporters. The two NBDs together bind and hydrolyze ATP, thereby providing the driving force for transport, while the TMDs participate in substrate recognition and translocation across the lipid membrane. However, some ABC genes are organized as half-transporters, which must form either homodimers or heterodimers to form a functional unit. The ABC exporters play a role in multidrug resistance to antibiotics and anticancer agents, and mutations in these proteins have been shown to cause severe human diseases such as cystic fibrosis.

5-45 | 2.59e-03 | ||
Six-transmembrane helical domain (6-TMD) of NHLP family bacteriocin export ABC transporters; This group includes the six-transmembrane helical domain (6-TMD) of the ABC subunit of NHLM (Nitrile Hydratase Leader Microcin) bacteriocin system, which contains ABC transporter (permease/ATP-binding fused protein) with a peptidase domain. ABC-transporter proteins in this group are predicted to be a subunit of a bacteriocin processing and export system, and they carry a proteolytic peptidase domain in their N-termini, termed as C39, which cleaves a double glycine (GG) motif-containing signal peptide from substrates before secretion. Pssm-ID: 350013 [Multi-domain] Cd Length: 294 Bit Score: 34.76 E-value: 2.59e-03
