DESCRIPTION

Also known as PTQA_ECOLI, chbA, celC. 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:10913118, PubMed:10913117). Also able to use N, N', N''-triacetyl chitotriose (GlcNAc3) (PubMed:10913117). Forms a complex with ChbB (EIIB) (PubMed:10913119, PubMed:10913122, PubMed:19959833). ChbA is a homotrimer (PubMed:10913122, PubMed:15654077, PubMed:19959833, PubMed:22593574). The interface of the homotrimer is stabilized by metal cations such as magnesium, copper or nickel (PubMed:15654077).
