Trehalose and maltose hydrolase (possible phosphorylase) [Carbohydrate transport and metabolism].

Glycosyl hydrolase family 65 central catalytic domain. This family of glycosyl hydrolases contains vacuolar acid trehalase and maltose phosphorylase.Maltose phosphorylase (MP) is a dimeric enzyme that catalyzes the conversion of maltose and inorganic phosphate into beta-D-glucose-1-phosphate and glucose. The central domain is the catalytic domain, which binds a phosphate ion that is proximal the the highly conserved Glu. The arrangement of the phosphate and the glutamate is thought to cause nucleophilic attack on the anomeric carbon atom. The catalytic domain also forms the majority of the dimerization interface.

maltose phosphorylase; Provisional

Glycosyl hydrolase family 65, N-terminal domain. This family of glycosyl hydrolases contains vacuolar acid trehalase and maltose phosphorylase.Maltose phosphorylase (MP) is a dimeric enzyme that catalyzes the conversion of maltose and inorganic phosphate into beta-D-glucose-1-phosphate and glucose. This domain is believed to be essential for catalytic activity although its precise function remains unknown.

oligosaccharide amylase. The name of this type of amylase is based on the characterization of an glucoamylase family enzyme from Thermoactinomyces vulgaris. The T. vulgaris enzyme was expressed in E. coli and, like other glucoamylases, it releases beta-D-glucose from starch. However, unlike previously characterized glucoamylases, this T. vulgaris amylase hydrolyzes maltooligosaccharides (maltotetraose, maltose) more efficiently than starch (1), indicating this enzyme belongs to a class of glucoamylase-type enzymes with oligosaccharide-metabolizing activity.
