EC 2.4.1.319     
Accepted name: β-1,4-mannooligosaccharide phosphorylase
Reaction: [(1→4)-β-D-mannosyl]n + phosphate = [(1→4)-β-D-mannosyl]n-1 + α-D-mannose 1-phosphate
Other name(s): RaMP2
Systematic name: 1,4-β-D-mannooligosaccharide:phosphate α-D-mannosyltransferase
Comments: The enzyme, isolated from the ruminal bacterium Ruminococcus albus, catalyses the reversible phosphorolysis of β-1,4-mannooligosaccharide with a minimum size of three monomers.
