ID   2.4.1.340
DE   1,2-beta-oligomannan phosphorylase.
CA   [(1->2)-beta-D-mannosyl](n) + phosphate = [(1->2)-beta-D-mannosyl](n-1) +
CA   alpha-D-mannose 1-phosphate.
CC   -!- The enzyme, originally characterized from the thermophilic anaerobic
CC       bacterium Thermoanaerobacter sp. X514, catalyzes a reversible
CC       reaction.
CC   -!- In the synthetic direction it produces oligosaccharides with a degree
CC       of polymerization (DP) of 3, 4 and 5.
CC   -!- The phosphorolysis reaction proceeds to completion, although activity
CC       is highest when the substrate has at least three residues. cf.
CC       EC 2.4.1.339.
