Protein Family Models

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.

phosphonate ABC transporter ATP-binding protein (PhnC) is a phosphonate-transporting ATPase that is part of the ABC transporter complex PhnCDE involved in the import of phosphonates and is responsible for energy coupling to the transport system

Phosphonates are a class of phosphorus-containing organic compound with a stable direct C-P bond rather than a C-O-P linkage. A number of bacterial species have operons, typically about 14 genes in size, with genes for ATP-dependent transport of phosphonates, degradation, and regulation of the expression of the system. Members of this protein family are the ATP-binding cassette component of tripartite ABC transporters of phosphonates.
