Reaction: N6-(D-fructosyl)-L-lysine = N6-(D-psicosyl)-L-lysine
Other name(s): frlC (gene name)
Systematic name: D-fructosyl-L-lysine 3-epimerase
Comments: The enzyme, characterized from the bacterium Escherichia coli, is involved in the catabolism of fructoseamines, amino acid sugar complexes that are formed non-enzymically.
