Glycoside hydrolase family 20, catalytic domain (IPR015883)

Short name: Glyco_hydro_20_cat

Overlapping homologous superfamilies

Domain relationships



Glycoside hydrolase family 20 (GH20) comprises enzymes with several known activities; beta-hexosaminidase (EC:; lacto-N-biosidase (EC:; beta-1,6-N-acetylglucosaminidase); and beta-6-SO3-N-acetylglucosaminidase. Carbonyl oxygen of the C-2 acetamido group of the substrate acts as the catalytic nucleophile/base in this family of enzymes.

This entry represents the glycoside hydrolase family 20 catalytic domain. This domain has a TIM barrel fold.
