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.

xylose ABC transporter ATP-binding protein (XylG) is the ATPase catalytic subunit of the ABC transporter complex XylFGH, and is responsible for coupling the energy of ATP hydrolysis to the import of xylose

Several bacterial species have enzymes xylose isomerase and xylulokinase enzymes for xylose utilization. Members of this protein family are the ATP-binding cassette (ABC) subunit of the known or predicted high-affinity xylose ABC transporter for xylose import. These genes, which closely resemble other sugar transport ABC transporter genes, typically are encoded near xylose utilization enzymes and regulatory proteins. Note that this form of the transporter contains two copies of the ABC transporter domain (PF00005).
