CC -!- FUNCTION: Protein and nucleotide deglycase that catalyzes the
CC deglycation of the Maillard adducts formed between amino groups of
CC proteins or nucleotides and reactive carbonyl groups of glyoxals. Thus,
CC functions as a protein deglycase that repairs methylglyoxal- and
CC glyoxal-glycated proteins, and releases repaired proteins and lactate
CC or glycolate, respectively. Deglycates cysteine, arginine and lysine
CC residues in proteins, and thus reactivates these proteins by reversing
CC glycation by glyoxals. Acts on early glycation intermediates
CC (hemithioacetals and aminocarbinols), preventing the formation of
CC Schiff bases and advanced glycation endproducts (AGE). Also functions
CC as a nucleotide deglycase able to repair glycated guanine in the free
CC nucleotide pool (GTP, GDP, GMP, dGTP) and in DNA and RNA. Is thus
CC involved in a major nucleotide repair system named guanine glycation
CC repair (GG repair), dedicated to reversing methylglyoxal and glyoxal
CC damage via nucleotide sanitization and direct nucleic acid repair.
CC Plays an important role in protecting cells from carbonyl stress.
