Protein Family Models

Several members are annotated as being of the abortive phage resistance system, in which case the family would be acting as the toxin for a type IV toxin-antitoxin resistance system. (from Pfam)

This family features a region found towards the C-terminus of oligopeptide ABC transporter ATP binding proteins, immediately following the ATP-binding domain (Pfam:PF00005). All characterised members appear able to be involved in the transport of oligopeptides or dipeptides. Some are important for sporulation or antibiotic resistance. Some dipeptide transporters also act on the heme precursor delta-aminolevulinic acid. (from Pfam)

ABC transporters for a large family of proteins responsible for translocation of a variety of compounds across biological membranes. ABC transporters are the largest family of proteins in many completely sequenced bacteria. ABC transporters are composed of two copies of this domain and two copies of a transmembrane domain Pfam:PF00664. These four domains may belong to a single polypeptide as in Swiss:P13569, or belong in different polypeptide chains. [1]. 1864505.

This HMM represents a domain found in the C-terminal regions of ABC transporter ATP binding proteins, immediately following the ATP-binding domain (PF00005). Many are involved in the transport of oligopeptides or dipeptides, including E. coli K-12 proteins DppD (dipeptide/heme), OppD and OppF (oligopeptide), DdpD and DdpF (D,D-dipeptide), etc.

ABC transporter ATP-binding protein is the ATPase catalytic subunit of an ATP transporter complex responsible for coupling the energy of ATP hydrolysis to the import of one or more from a variety of substrates including dipeptides and oligopeptides
