PTS system N,N'-diacetylchitobiose-specific EIIC component

Gene

chbC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II ChbABC PTS system is involved in the transport of the chitin disaccharide N,N'-diacetylchitobiose (GlcNAc2) (PubMed:10913117). Also able to use N,N',N''-triacetyl chitotriose (GlcNAc3) (PubMed:10913117).1 Publication1 Publication

Caution

Was originally (PubMed:2179047) characterized as part of a cryptic cel operon for a cellobiose degradation system. The Cel+ phenotype is due to mutations making expression chitobiose-independent and altering the substrate specificity.1 Publication
