Basic amino acid antiporter family

The Basic Amino Acid Antiporter (ArcD) family (TC# 2.A.118) is a constituent of the IT superfamily.[1][2][3] This family consists of proteins from Gram-negative and Gram-positive bacteria (e.g., Streptococcus, Escherichia, Salmonella, Fusobacterium and Borrelia species). The proteins are of about 480 amino acyl residues (aas) in length and have 10-12 putative transmembrane segments (TMSs). Functionally characterized homologues are in the DcuC (TC #2.A.61) and ArsB (TC #2.A.4) families. Some members of the family probably catalyze arginine/ornithine or citruline/ornithine antiport.[4][5]
