Protein deglycase.
based on mapping to UniProt Q99497
(1) An N(omega)-(1-hydroxy-2-oxopropyl)-[protein]-L-arginine + H(2)O = a [protein]-L-arginine + lactate. (2) An N(6)-(1-hydroxy-2-oxopropyl)-[protein]-L-lysine + H(2)O = a [protein]-L-lysine + lactate. (3) An S-(1-hydroxy-2-oxopropyl)-[protein]-L-cysteine + H(2)O = a [protein]-L-cysteine + lactate.
-!- The enzyme, previously thought to be a glyoxalase, acts on glycated L-arginine, L-lysine, and L-cysteine residues within proteins that have been attacked and modified by glyoxal or 2-oxopropanal. -!- The attack forms hemithioacetal in the case of cysteines and aminocarbinols in the case of arginines and lysines. -!- The enzyme repairs the amino acids, releasing glycolate or lactate (70-80% (S)-lactate and 20-30% (R)-lactate), depending on whether the attacking agent was glyoxal or 2-oxopropanal, respectively.
