A glycosynthase derived from an inverting GH19 chitinase from the moss Bryum coronatum.

Abstract excerpt

BcChi-A, a GH19 chitinase from the moss Bryum coronatum, is an endo-acting enzyme that hydrolyses the glycosidic bonds of chitin, (GlcNAc)(n) [a β-1,4-linked polysaccharide of GlcNAc (N-acetylglucosamine) with a polymerization degree of n], through an inverting mechanism. When the wild-type enzyme was incubated with α-(GlcNAc)2-F [α-(GlcNAc)(2) fluoride] in the absence or presence of (GlcNAc)(2), (GlcNAc)(2) and...
