This domain family is found in bacteria, archaea and eukaryotes, and is approximately 30 amino acids in length. The family is found in association with pfam00005. There is a conserved AYLG sequence motif. This family is the C terminal of an ATP dependent branched-chain amino acid transporter. This domain is essential for LPS transport, through critical interactions with Walker A and switch helix domains.
