HHsearch alignment for GI: 254780539 and conserved domain: cd06574

>cd06574 TM_PBP1_branched-chain-AA_like Transmembrane subunit (TM) of Periplasmic Binding Protein (PBP)-dependent ATP-Binding Cassette (ABC) transporters which are involved in the uptake of branched-chain amino acids (AAs), as well as TMs of transporters involved in the uptake of monosaccharides including ribose, galactose, and arabinose. These transporters generally bind type 1 PBPs. PBP-dependent ABC transporters consist of a PBP, two TMs, and two cytoplasmic ABCs, and are mainly involved in importing solutes from the environment. The solute is captured by the PBP which delivers it to a gated translocation pathway formed by the two TMs. The two ABCs bind and hydrolyze ATP and drive the transport reaction. This group includes Escherichia coli LivM and LivH, two TMs which heterodimerize to form the translocation pathway of the E. coli branched-chain AA LIV-1/LS transporter. This transporter is comprised of two TMs (LivM and LivH), two ABCs (LivG and LivF), and one of two alternative PBP
