Accepted name: D-lactate dehydrogenase (quinone)
Reaction: (R)-lactate + a quinone = pyruvate + a quinol
Other name(s): dld (gene name)
Systematic name: (R)-lactate:quinone 2-oxidoreductase
Comments: The enzyme is an FAD-dependent peripheral membrane dehydrogenase that participates in respiration. Electrons derived from D-lactate oxidation are transferred to the membrane soluble quinone pool.
