Summary
The chb operon is induced by N,N'-diacetylchitobiose. [More information is available at EcoGene: EG10144]. ChbF is a diacetylchitobiose-6-phosphate hydrolase responsible for converting diacetylchitobiose-6-phosphate to N-acetyl-D-glucosamine and N-acetyl-D-glucosamine-6-phosphate . [More information is available at EcoCyc: EG10144].
