periplasmic ligand-binding domain of uncharacterized ABC-type transport systems predicted to be involved in uptake of amino acids, peptides, or inorganic ions
This group includes the type 1 periplasmic ligand-binding domain of uncharacterized ABC (ATPase Binding Cassette)-type transport systems that are predicted to be involved in the uptake of amino acids, peptides, or inorganic ions. This subgroup has high sequence similarity to members of the family of hydrophobic amino acid transporters (HAAT), such as leucine-isoleucine-valine binding protein (LIVBP); its ligand specificity has not been determined experimentally, however.
