This entry represents a beta-sandwich domain found at the C-terminal of exo-beta-D-glucosaminidase GLMA from Thermococcus kodakarensis and similar archaeal proteins. It is an exo-type enzyme that specifically cleaves the non-reducing terminal glycosidic bond of chitooligosaccharides, being involved in chitin degradation [1-3].	Domain
A, B	PF22369	GLMA-like, glycosyl hydrolase domain (GLMA-like_GHD)	GLMA-like, glycosyl hydrolase domain	This entry represents an all-beta domain (GHD) found towards the C-terminal of exo-beta-D-glucosaminidase GLMA from Thermococcus kodakarensis and similar archaeal proteins, just before the C-terminal domain (Pfam:PF22345). It is an exo-type enzyme th ...	This entry represents an all-beta domain (GHD) found towards the C-terminal of exo-beta-D-glucosaminidase GLMA from Thermococcus kodakarensis and similar archaeal proteins, just before the C-terminal domain (Pfam:PF22345). It is an exo-type enzyme that specifically cleaves the non-reducing terminal glycosidic bond of chitooligosaccharides, being involved in chitin degradation [1].	Domain
