N-acetyl glucosamine, glucosamine and chitobiose
play an important role in chemotaxis and induce the chitinase production [37,38,39].
The synthesis of chitoheptaose has been achieved by using chitopentaose oxazoline as glycosyl donor and chitobiose
as glycosyl acceptor catalyzed by a mutant chitinase.
Cloning and expression of chitinase A from Serratia marcescens for large-scale preparation of N, N diacetyl chitobiose
As the second-most abundant biopolymer after cellulose, chitin is mainly synthesized via a biosynthetic process by an enormous number of living organisms such as shrimp, crab, tortoise, and insects and can also be synthesized by a nonbiosynthetic pathway through chitinase-catalyzed polymerization of a chitobiose
fischeri then migrate through the pores in response to a chitobiose
gradient to which they undergo chemotaxis (Mandel et al.
The average molecular weight of COS was 1,500 Da and the major components of COS were chitobiose
, chitotriose, chitotetraose, chitopentaose and chitohexaose (Li et al.
Chitin is the organic skeletal substance of the shells of crustaceans and may be considered to be a linear polymer of chitobiose
, an aminopolysaccharide with a molecular weight of several hundred thousand.
