Mannosylfructose-phosphate synthase

Mannosylfructose-phosphate synthase (, mannosylfructose-6-phosphate synthase, MFPS) is an enzyme with systematic name GDP-mannose:D-fructose-6-phosphate 2-alpha-D-mannosyltransferase. This enzyme catalyses the following chemical reaction


 * GDP-mannose + D-fructose 6-phosphate $$\rightleftharpoons$$ GDP + beta-D-fructofuranosyl-alpha-D-mannopyranoside 6F-phosphate

This enzyme, from the soil proteobacterium and plant pathogen Agrobacterium tumefaciens strain C58, requires Mg2+ or Mn2+ for activity.
