FunFam 313: Glycosyltransferase family 1 protein

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Mannosylfructose-phosphate synthase. [EC: 2.4.1.246]
GDP-mannose + D-fructose 6-phosphate = GDP + beta-D-fructofuranosyl- alpha-D-mannopyranoside 6(F)-phosphate.
  • 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.
