4-O-beta-D-mannosyl-D-glucose phosphorylase (EC 2.4.1.281, mannosylglucose phosphorylase) is an enzyme with systematic name 4-O-beta-D-mannopyranosyl-D-glucopyranose:phosphate alpha-D-mannosyltransferase.^[1] This enzyme catalyses the following chemical reaction

4-O-beta-D-mannopyranosyl-D-glucopyranose + phosphate $\rightleftharpoons$ D-glucose + alpha-D-mannose 1-phosphate

This enzyme forms part of a mannan catabolic pathway in the anaerobic bacterium Bacteroides fragilis NCTC 9343.
