[https://www.uniprot.org/uniprot/MGLB_ECOLI 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).<ref>PMID:3057628</ref> <ref>PMID:4927373</ref> <ref>PMID:6294056</ref> <ref>PMID:1719366</ref> <ref>PMID:6294056</ref>
