Fructosamines are compounds that result from glycation reactions between a sugar and a primary amine, followed by isomerization via the Amadori rearrangement. In fructoselysine degradation, fructoselysine firstly converts to 1-[(5-Amino-5-carboxypentyl)amino]-1-deoxyfructose by protein frlC, and then 1-[(5-Amino-5-carboxypentyl)amino]-1-deoxyfructose is transformed to fructoselysine-6-phosphate by fructoselysine kinase which is powered by ATP. Fructoselysine-6-phosphate finally degrades to β-D-Glucose 6-phosphate and L-lysine by fructoselysine 6-phosphate deglycase.
