(1->4)-2-acetamido-2-deoxy-beta-D-glucan diacetylchitobiohydrolase (non-reducing end)

Hydrolysis of N,N'-diacetylchitobiose from the non-reducing end of chitin and chitodextrins.

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).
