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.
