IUBMB Enzyme Nomenclature

EC 1.3.1.110

Accepted name: lactate dehydrogenase (NAD+, ferredoxin)

Reaction: lactate + 2 NAD+ + 2 reduced ferredoxin [iron-sulfur] cluster = pyruvate + 2 NADH + 2 oxidized ferredoxin [iron-sulfur] cluster

Other name(s): electron bifurcating LDH/Etf complex

Systematic name: lactate:NAD+, ferredoxin oxidoreductase

Comments: The enzyme, isolated from the bacterium Acetobacterium woodii, uses flavin-based electron confurcation to drive endergonic lactate oxidation with NAD+ as oxidant at the expense of simultaneous exergonic electron flow from reduced ferredoxin to NAD+.
