Short name: ABC_transpr_MglA

Family relationships

None.

Description

Bacterial high affinity transport systems are involved in active transport of solutes across the cytoplasmic membrane. Most of the bacterial ABC (ATP-binding cassette) importers are composed of one or two transmembrane permease proteins, one or two nucleotide-binding proteins and a highly specific periplasmic solute-binding protein. In Gram-negative bacteria the solute-binding proteins are dissolved in the periplasm, while in archaea and Gram-positive bacteria, their solute-binding proteins are membrane-anchored lipoproteins [PMID: 8003968, PMID: 18310026].

This entry contains the ATP-binding protein MglA that is part of the ABC transporter complex, mglABC, involved in the import of galactose and/or methyl galactoside. The complex is composed of two ATP-binding proteins (MglA), two transmembrane proteins (MglC) and a solute-binding protein (MglB) [PMID: 4981309, PMID: 4618738].
