Ligands:,
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

MGLB_ECOLI Part of the ABC transporter complex MglABC involved in galactose/methyl galactoside import (Probable). In addition, binds D-galactose and D-glucose and plays a role in the chemotaxis towards these two sugars by interacting with the Trg chemoreceptor (PubMed:3057628, PubMed:4927373). Chemotaxis requires MglB, but not MglA or MglC (PubMed:6294056).[1] [2] [3] [4] [5]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
