FGGY family of carbohydrate kinases signatures


It has been shown [1] that four different type of carbohydrate kinases seem to be evolutionary related. These enzymes are:

  • L-fuculokinase (EC (gene fucK).
  • Gluconokinase (EC (gene gntK).
  • Glycerokinase (EC (gene glpK).
  • Xylulokinase (EC (gene xylB).
  • L-xylulose kinase (EC (gene lyxK).

These enzymes are proteins of from 480 to 520 amino acid residues.

As consensus patterns for this family of kinases we selected two conserved regions, one in the central section, the other in the C-terminal section.
