ENZYME entry: EC 2.4.1.246

Accepted Name
mannosylfructose-phosphate synthase.
Alternative Name(s)
mannosylfructose-6-phosphate synthase.
MFPS.
Reaction catalysed
beta-D-fructose 6-phosphate + GDP-alpha-D-mannose <=> beta-D-fructofuranosyl alpha-D-mannopyranoside 6(F)-phosphate + GDP + H(+)
Comment(s)
  • GDP-mannose can be replaced by ADP-mannose but with a concomitant decrease in activity.
  • The product of this reaction is dephosphorylated by EC 3.1.3.79 to form the non-reducing disaccharide mannosylfructose, which is the major endogenous osmolyte produced by several alpha-proteobacteria in response to osmotic stress.
  • The F in the product name is used to indicate that the fructose residue of sucrose carries the substituent.
