Sysname
cellobiose 2-epimerase
Reaction(IUBMB)
cellobiose = 4-O-beta-D-glucopyranosyl-D-mannose [RN:
R01445 R06245 ]
Reaction(KEGG)
Substrate
Product
4-O-beta-D-glucopyranosyl-D-mannose [CPD:
C02964 ]
Comment
The enzyme catalyses the interconversion between D-glucose and D-mannose residues at the reducing end of beta-1,4-linked disaccharides by epimerizing the hydroxyl group at the C-2 position of the glucose moiety.
