Reaction: (R)-S-lactoylglutathione = glutathione + methylglyoxal

Glossary: methylglyoxal = 2-oxopropanal

Other name(s): methylglyoxalase; aldoketomutase; ketone-aldehyde mutase; glyoxylase I; (R)-S-lactoylglutathione methylglyoxal-lyase (isomerizing)

Systematic name: (R)-S-lactoylglutathione methylglyoxal-lyase (isomerizing; glutathione-forming)

Comments: Also acts on 3-phosphoglycerol-glutathione.
