Protoporphyrinogen IX dehydrogenase (menaquinone) (EC 1.3.5.3, HemG) is an enzyme with systematic name protoporphyrinogen IX:menaquinone oxidoreductase.[1] This enzyme catalyses the following chemical reaction
- protoporphyrinogen IX + 3 menaquinone [math]\displaystyle{ \rightleftharpoons }[/math] protoporphyrin IX + 3 menaquinol
This enzyme enables Escherichia coli to synthesize heme in both aerobic and anaerobic environments.
