IUBMB Enzyme Nomenclature


Accepted name: fructoselysine 6-kinase

Reaction: ATP + N6-(D-fructosyl)-L-lysine = ADP + N6-(6-phospho-D-fructosyl)-L-lysine

Other name(s): frlD (gene name)

Systematic name: ATP:D-fructosyl-L-lysine 6-phosphotransferase

Comments: The enzyme, characterized from the bacterium Escherichia coli, has very little activity with fructose.
