This domain is related to glutamine amidotransferase enzymes, but the catalytic residues are replaced by non functional amino acids. This domain ...	This is non catalytic domain B of beta-galactosidase enzymes belong to the glycosyl hydrolase 42 family. This domain is related to glutamine amidotransferase enzymes, but the catalytic residues are replaced by non functional amino acids. This domain is involved in trimerisation [1].	Domain

It is an exo-type enzyme that specifically cleaves the non-reducing terminal glycosi ...	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, C, D	PF22369	GLMA-like, second domain (GLMA_2nd)	GLMA-like, second domain	This entry represents the second domain 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-redu ...
