EXTRA NOTES |
Biochem/physiol Actions:In chitinolytic bacteria, such as Vibrio, Streptomyces and Serratia, N,N′-Diacetylchitobiose (GlcNAc2) is not only a major breakdown product of chitinase, but it is also the smallest substance that induces chitinase production. It can also be utilized as a carbon source by E. coli, which does not express chitinases, but is exposed to GlcNAc2 produced by intestinal chitinolytic bacteria. In most organisms, the uptake of GlcNAc2 occurs via the phosphoenolpyruvate:glycose phosphotransferase system (PTS). GlcNAc2 has also been used as a substrate or inhibitor to study the activity of glycolytic enzymes. sigmaaldrich |
