A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.4.1.340

Accepted Name
1,2-beta-oligomannan phosphorylase.
Reaction catalysed
((1->2)-beta-D-mannosyl)(n) + phosphate <=> ((1->2)-beta-D-mannosyl)(n-1) + alpha-D-mannose 1-phosphate
Comment(s)
  • The enzyme, originally characterized from the thermophilic anaerobic bacterium Thermoanaerobacter sp. X514, catalyzes a reversible reaction.
  • In the synthetic direction it produces oligosaccharides with a degree of polymerization (DP) of 3, 4 and 5.
  • The phosphorolysis reaction proceeds to completion, although activity is highest when the substrate has at least three residues.
  • Cf. EC 2.4.1.339.
