4.2.1.130

Accepted name:

D-lactate dehydratase

Reaction:

(R)-lactate = 2-oxopropanal + H₂O

Glossary:

methylglyoxal = 2-oxopropanal
(R)-lactate = D-lactate

Other name(s):

glyoxylase III; GLO3

Systematic name:

(R)-lactate hydro-lyase

Comments:

The enzyme, described from the fungi Candida albicans and Schizosaccharomyces pombe, converts 2-oxopropanal to (R)-lactate in a single glutathione (GSH)-independent step. The other known route for this conversion is the two-step GSH-dependent pathway catalysed by EC 4.4.1.5 (lactoylglutathione lyase) and EC 3.1.2.6 (hydroxyacylglutathione hydrolase).
