mass-spectrometric identification of the fructosamine residues that are removed from hemoglobin in intact erythrocytes as a result of the action of fructosamine-3-kinase: Lys16, Lys61 and Lys139 in the alpha-chain of hemoglobin, Val1, Lys17, Lys59, Lys66, Lys132, and Lys144 in the beta-chain of hemoglobin. Some (e.g. Lys139 in the alph-chain of hemoglobin) are readily phosphorylated to a maximal extent by fructosamine-3-kinase in vitro whereas others (e.g. Val1 in the beta-chain of hemoglobin) are slowly and only very partially phosphorylated

nonenzymatic glycation is an important factor in the pathogenesis of diabetic complications. Key early intermediates in this process are fructosamines, such as protein-bound fructoselysines. The fructosamine most frequently encountered in nature is fructoselysine. Fructosamine-3-kinase is part of an ATP-dependent system for removing carbohydrates from nonenzymatically glycated proteins and protecting cells from the deleterious effects of nonenzymatic glycation

protein repair mechanism. Fructosamine 3-kinase phosphorylates with high affinity both low-molecular-mass and protein-bound fructosamines on the third carbon of their deoxyfructose moiety, leading to the formation of fructosamine 3-phosphates. The latter are unstable and spontaneously decompose into inorganic phosphate and 3-deoxyglucosone, with concomitant regeneration of the unglycated amine

repairing glucose-mediated non-enzymatic modification of proteins. The function of fructosamine-3-kinase is seen in catalysing the ATP-dependent phosphorylation of the protein-bound fructosamine (Amadori compound) fructoselysine, which is the first stable intermediate resulting from the Maillard reaction between glucose and lysine, on its 3-hydroxy group to 3-phosphofructosyllysine. The phosphorylation destabilises the fructose-amine linkage leading to a spontaneous decomposition of 3-phosphofructosyllysine to the unmodified lysine residue as well as to 3-deoxyglucosulose and inorganic phosphate

[histone]-N6-D-fructosyl-L-lysine, [hemoglobin]-N6-D-fructosyl-L-lysine. Similar experiments with other glycated proteins, including bovine serum albumin, and lysozyme indicate that fructoselysine residues on glycated proteins are readily phosphorylated by fructosamine 3-kinase, apparently irrespective of the protein. Phosphorylation destablilizes the fructoselysine adduct and leads to its spontaneous decomposition

the fructosamines bound to Lys139alpha, located near the C-terminus of the alpha subunits, and Lys16alpha, located on a loop of the alpha subunits, are good substrates. The N-terminal glycated valine is a poor substrate, consistent with free fructosevaline being a much poorer substrate than free fructoselysine
