EC 3.2.1.201 Details
EC number
3.2.1.201
Accepted name
exo-chitinase (reducing end)
Reaction
Hydrolysis of N,N′-diacetylchitobiose from the reducing end of chitin and chitodextrins.
Other name(s)
chiA (gene name)
Systematic name
(1→4)-2-acetamido-2-deoxy-β-D-glucan diacetylchitobiohydrolase (reducing end)
Comment
The enzyme hydrolyses the second glycosidic (1→4) linkage from reducing ends of chitin and chitodextrin molecules, liberating N,N′-diacetylchitobiose disaccharides. cf. EC 3.2.1.200, exo-chitinase (non-reducing end).
