Entry |
|
Name |
exo-chitinase (non-reducing end);
chiB (gene name)
|
Class |
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
|
Sysname |
(1->4)-2-acetamido-2-deoxy-beta-D-glucan diacetylchitobiohydrolase (non-reducing end)
|
Reaction(IUBMB) |
Hydrolysis of N,N'-diacetylchitobiose from the non-reducing end of chitin and chitodextrins.
|
Comment |
The enzyme hydrolyses the second glycosidic (1->4) linkage from non-reducing ends of chitin and chitodextrin molecules, liberating N,N'-diacetylchitobiose disaccharides. cf. EC 3.2.1.201, exo-chitinase (reducing end).
