2.4.1.339

Accepted name:

β-1,2-mannobiose phosphorylase

Reaction:

β-D-mannopyranosyl-(1→2)-D-mannopyranose + phosphate = D-mannopyranose + α-D-mannose 1-phosphate

Systematic name:

β-D-mannopyranosyl-(1→2)-D-mannopyranose:phosphate α-D-mannosyltransferase

Comments:

The enzyme, originally characterized from the thermophilic anaerobic bacterium Thermoanaerobacter sp. X514, catalyses a reversible reaction. cf. EC 2.4.1.340, 1,2-β-oligomannan phosphorylase.
