Glycosyl hydrolase family 130; uncharacterized. This subfamily contains glycosyl hydrolase family 130 (GH130) proteins, as classified by the carbohydrate-active enzymes database (CAZY), most of which are as yet uncharacterized. GH130 enzymes are phosphorylases and hydrolases for beta-mannosides, and include beta-1,4-mannosylglucose phosphorylase (EC 2.4.1.281), beta-1,4-mannooligosaccharide phosphorylase (EC 2.4.1.319), beta-1,4-mannosyl-N-acetyl-glucosamine phosphorylase (EC 2.4.1.320), beta-1,2-mannobiose phosphorylase (EC 2.4.1.-), beta-1,2-oligomannan phosphorylase (EC 2.4.1.-) and beta-1,2-mannosidase (EC 3.2.1.-). They possess 5-bladed beta-propeller domains similar to families 32, 43, 62, 68, 117 (GH32, GH43, GH62, GH68, GH117). GH130 enzymes are involved in the bacterial utilization of mannans or N-linked glycans. Beta-1,4-mannosylglucose phosphorylase is involved in degradation of beta-1,4-D-mannosyl-N-acetyl-D-glucosamine linkages in the core of N-glycans; it produces alpha-mannose 1-phosphate and glucose from 4-O-beta-D-mannosyl-D-glucose and inorganic phosphate, using a critical catalytic Asp as a proton donor.

Glycoside hydrolase family 130 such as Listeria innocua beta-1,2-mannobiose phosphorylase. This subfamily contains the glycosyl hydrolase family 130 (GH130), as classified by the carbohydrate-active enzymes database (CAZY), enzymes that are phosphorylases and hydrolases for beta-mannosides, and includes Listeria innocua beta-1,2-mannobiose phosphorylase (Lin0857). hey possess 5-bladed beta-propeller domains similar to families 32, 43, 62, 68, 117 (GH32, GH43, GH62, GH68, GH117). GH130 enzymes are involved in the bacterial utilization of mannans or N-linked glycans. Structure of Lin0857 shows beta-1,2-mannotriose bound in a U-shape, interacting with a phosphate analog at both ends. Lin0857 has a unique dimer structure connected by a loop, with a significant open-close loop displacement observed for substrate entry. A long loop, which is exclusively present in Lin0857, covers the active site to limit the pocket size.

Glycoside hydrolase family 130. Members of the glycosyl hydrolase family 130, as classified by the carbohydrate-active enzymes database (CAZY), are phosphorylases and hydrolases for beta-mannosides, and include beta-1,4-mannosylglucose phosphorylase (EC 2.4.1.281), beta-1,4-mannooligosaccharide phosphorylase (EC 2.4.1.319), beta-1,4-mannosyl-N-acetyl-glucosamine phosphorylase (EC 2.4.1.320), beta-1,2-mannobiose phosphorylase (EC 2.4.1.-), beta-1,2-oligomannan phosphorylase (EC 2.4.1.-) and beta-1,2-mannosidase (EC 3.2.1.-). They possess 5-bladed beta-propeller domains similar to families 32, 43, 62, 68, 117 (GH32, GH43, GH62, GH68, GH117). GH130 enzymes are involved in the bacterial utilization of mannans or N-linked glycans.

This family includes Ruminococcus albus 4-O-beta-D-mannosyl-D-glucose phosphorylase (RaMP1) and beta-(1,4)-mannooligosaccharide phosphorylase (RaMP2), enzymes that phosphorolyze beta-mannosidic linkages at the non-reducing ends of their substrates, and have substantially diverse substrate specificity that are determined by three loop regions.
