BRITE hierarchy
Sysname
beta-D-galactosyl-(1->4)-L-rhamnose:phosphate 1-alpha-D-galactosyltransferase
Reaction(IUBMB)
beta-D-galactosyl-(1->4)-L-rhamnose + phosphate = L-rhamnose + alpha-D-galactose 1-phosphate [RN:R09632]
Reaction(KEGG)
Substrate
beta-D-galactosyl-(1->4)-L-rhamnose [CPD:C19758];
phosphate [CPD:C00009]
Product
L-rhamnose [CPD:C00507];
alpha-D-galactose 1-phosphate [CPD:C00446]
Comment
The enzyme from Clostridium phytofermentans is also active towards towards beta-D-galactosyl derivatives of L-mannose, L-lyxose, D-glucose, 2-deoxy-D-glucose, and D-galactose in this order. Differs from 1,3-beta-galactosyl-N-acetylhexosamine phosphorylase (EC 2.4.1.211) in being active towards L-rhamnose and inactive towards N-acetyl hexosamine derivatives.
