Function and Biology Details

Reaction catalysed:
(1) An N(omega)-(1-hydroxy-2-oxopropyl)-[protein]-L-arginine + H(2)O = a [protein]-L-arginine + (R)-lactate. (2) An N(6)-(1-hydroxy-2-oxopropyl)-[protein]-L-lysine + H(2)O = a [protein]-L-lysine + (R)-lactate. (3) An S-(1-hydroxy-2-oxopropyl)-[protein]-L-cysteine + H(2)O = a [protein]-L-cysteine + (R)-lactate.
