A, B	PF21365	Glycosyl hydrolase family 31 C-terminal domain (Glyco_hydro_31_3rd)	Glycosyl hydrolase family 31 C-terminal domain	Glycosyl hydrolases are key enzymes of carbohydrate metabolism. Family 31 comprises of enzymes that are, or similar to, alpha- galactosidases. This entry represents the 3rd beta sandwich domain.	Domain
A, B	PF16990	Carbohydrate binding module (family 35) (CBM_35)	Carbohydrate binding module (family 35)	This is a mannan-specific carbohydrate binding domain, previously known as the X4 module [1]. Unlike other carbohydrate binding modules, binding to substrate causes a conformational change [2].	Domain
A, B	PF17137	Domain of unknown function (DUF5110) (DUF5110)	Domain of unknown function (DUF5110)	-	Family
A, B	PF01055	Glycosyl hydrolases family 31 TIM-barrel domain (Glyco_hydro_31_2nd)	Glycosyl hydrolases family 31 TIM-barrel domain	Glycosyl hydrolases are key enzymes of carbohydrate metabolism. Family 31 comprises of enzymes that are, or similar to, alpha- galactosidases. This entry corresponds to the second domain of family 31 enzymes and adopts a TIM-barrel fold.	Domain
