FN3K catalyzes the phosphorylation of fructosamines which may result in deglycation, the non- enzymatic reaction of glucose with primary amines followed by Amadori re-arrangement. Phosphorylation of fructosamines may initiate metabolism of the modified amine and lead to the de-glycation of fructoselysine and of glycated proteins.
