alpha-glucosidase YihQ-like. YihQ is a bacterial alpha-glucosidase with a conserved glycosyl hydrolase family 31 (GH31) domain that catalyzes the release of an alpha-glucosyl residue from the non-reducing end of alpha-glucoside substrates such as alpha-glucosyl fluoride. Orthologs of YihQ that have not yet been functionally characterized are present in plants and fungi. YihQ has sequence similarity to other GH31 enzymes such as CtsZ, a 6-alpha-glucosyltransferase from Bacillus globisporus, and YicI, an alpha-xylosidase from Echerichia coli. These latter two belong to different GH31 subfamilies than YihQ. In bacteria, YihQ (along with YihO) is important for bacterial O-antigen capsule assembly and translocation.

alpha-glucosidase; Provisional

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.
