Comments (originally from EcoCyc) ChbA-ChbB-ChbC, the N,N'-diacetylchitobiose PTS permease (previously designated CelABC, the Cellobiose/Arbutin/Salicin PTS permease), belongs to the functional superfamily of the phosphoenolpyruvate (PEP)-dependent, sugar transporting phosphotransferase system (PTS). The PTS transports and simultaneously phosphorylates its sugar substrates in a process called group translocation. The ChbABC complex takes up exogenous N,N'-diacetylchitobiose, releasing the phosphate ester into the cell cytoplasm in preparation for hydrolysis and metabolism, primarily via glycolysis . The chb operon is subject to positive control by the cyclic AMP-cyclic AMP receptor protein complex.
