Fructosamine 3 kinase

FN3K, fructosamine-3-kinase
A high concentration of glucose can result in non-enzymatic oxidation of proteins by reaction of glucose and lysine residues (glycation). Proteins modified in this way, fructosamines, are less active or functional. This gene encodes an enzyme which catalyzes the phosphorylation of fructosamines which may result in deglycation.

Mosca et al., In Clin Chem Lab Med, Aug 2015
The identification of fructosamine 3-kinase (FN3K), an enzyme involved in protein deglycation, a new form of protein repair, is of great interest.

Review
Gonos et al., Athens, Greece. In Mol Aspects Med, 2014
With regard to protein repair, only few repair mechanisms have been evidenced including the reduction of methionine sulfoxide residues by the methionine sulfoxide reductases, the conversion of isoaspartyl residues to L-aspartate by L-isoaspartate methyl transferase and deglycation by phosphorylation of protein-bound fructosamine by fructosamine-3-kinase.
A new HPLC-based assay for the measurement of fructosamine-3-kinase (FN3K) and FN3K-related protein activity in human erythrocytes.
Henle et al., In Clin Chem Lab Med, 2014
BACKGROUND: An impact on glycation, and possibly on diabetic complications, is attributed to fructosamine-3-kinase (FN3K) and its related protein (FN3K-RP) because they degrade Amadori compounds in vivo.
Genetic variability in enzymes of metabolic pathways conferring protection against non-enzymatic glycation versus diabetes-related morbidity and mortality.
Kaňková et al., In Clin Chem Lab Med, 2014
BACKGROUND: We hypothesized that genetic variability in genes encoding enzymes metabolizing glycolytic intermediates produced in excess under hyperglycemic conditions [i.e., transketolase (TKT), transaldolase, TKT-like protein 1, fructosamine 3-kinase (FN3K), glyoxalase 1 and glucose-6-phosphate dehydrogenase] could influence progression of diabetic nephropathy (DN) and diabetes-related morbidity and mortality.

Kalousová et al., Praha, Czech Republic. In Physiol Res, 2013
Several enzymes such as fructosamine 3-kinase (FN3K) and glyoxalase I (GLO I) are crucial in preventing glycation processes.

Kalinski et al., Magdeburg, Germany. In Plos One, 2013
However, mRNA accumulation of the aldehyde- and AGE-defence enzymes glyoxalase-1 and -2 (GLO1, GLO2) as well as fructosamine-3-kinase (FN3K) was not significantly altered.
Enzymatic repair of Amadori products.
Review
Veiga-da-Cunha et al., Brussels, Belgium. In Amino Acids, 2012
Fructosamine-3-kinase (FN3K), an enzyme found in mammals and birds, phosphorylates fructosamines on the third carbon of their sugar moiety, making them unstable and causing them to detach from proteins.

MAGIC Investigators et al., Boston, United States. In Bmc Med Genet, 2011
We tested the hypotheses that there is race-ethnic variation in 1) HbA1c-associated risk allele frequencies (RAFs) for SNPs near SPTA1, HFE, ANK1, HK1, ATP11A, FN3K, TMPRSS6, G6PC2, GCK, MTNR1B; 2) association of SNPs with HbA1c and 3) association of SNPs with mortality.
The physiological substrates of fructosamine-3-kinase-related-protein (FN3KRP) are intermediates of nonenzymatic reactions between biological amines and ketose sugars (fructation products).

The physiological function of fructosamine-3-kinase (FN3K) is relatively well understood.
