Reaction: 3-O-α-D-glucopyranosyl-D-glucopyranose + phosphate = D-glucose + β-D-glucose 1-phosphate
Glossary: 3-O-α-D-glucopyranosyl-D-glucopyranose = nigerose
Other name(s): cphy1874 (gene name)
Systematic name: 3-O-α-D-glucopyranosyl-D-glucopyranose:phosphate β-D-glucosyltransferase
Comments: The enzymes from Clostridium phytofermentans is specific for nigerose, and shows only 0.5% relative activity with kojibiose (cf. EC 2.4.1.230, kojibiose phosphorylase)
