CtsY (cyclic tetrasaccharide-synthesizing enzyme Y)-like. CtsY is a bacterial 3-alpha-isomaltosyltransferase, first identified in Arthrobacter globiformis, that produces cyclic tetrasaccharides together with a closely related enzyme CtsZ. CtsY and CtsZ both have a glycosyl hydrolase family 31 (GH31) catalytic domain; CtsZ belongs to a different subfamily. All GH31 enzymes cleave a terminal carbohydrate moiety from a substrate that varies considerably in size, depending on the enzyme, and may be either a starch or a glycoprotein.

Alpha-glucosidase, glycosyl hydrolase family GH31 [Carbohydrate transport and metabolism].

Glycosyl hydrolases family 31. Glycosyl hydrolases are key enzymes of carbohydrate metabolism. Family 31 comprises of enzymes that are, or similar to, alpha- galactosidases.

alpha-xylosidase YicI-like. YicI alpha-xylosidase is a glycosyl hydrolase family 31 (GH31) enzyme that catalyzes the release of an alpha-xylosyl residue from the non-reducing end of alpha-xyloside substrates such as alpha-xylosyl fluoride and isoprimeverose. YicI forms a homohexamer (a trimer of dimers). All GH31 enzymes cleave a terminal carbohydrate moiety from a substrate that varies considerably in size, depending on the enzyme, and may be either a starch or a glycoprotein. The YicI family corresponds to subgroup 4 in the Ernst et al classification of GH31 enzymes.

glucosidase NET37. NET37 (also known as KIAA1161) is a human lamina-associated nuclear envelope transmembrane protein. A member of the glycosyl hydrolase family 31 (GH31) , it has been shown to be required for myogenic differentiation of C2C12 cells. Related proteins are found in eukaryotes and prokaryotes. Enzymes of the GH31 family possess a wide range of different hydrolytic activities including alpha-glucosidase (glucoamylase and sucrase-isomaltase), alpha-xylosidase, 6-alpha-glucosyltransferase, 3-alpha-isomaltosyltransferase and alpha-1,4-glucan lyase. All GH31 enzymes cleave a terminal carbohydrate moiety from a substrate that varies considerably in size, depending on the enzyme, and may be either a starch or a glycoprotein.
