Aldehyde-alcohol dehydrogenase

Gene

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

This enzyme has three activities: ADH, ACDH, and PFL-deactivase. In aerobic conditions it acts as a hydrogen peroxide scavenger. The PFL deactivase activity catalyzes the quenching of the pyruvate-formate-lyase catalyst in an iron, NAD, and CoA dependent reaction.

Catalytic activityi

A primary alcohol + NAD+ = an aldehyde + NADH.
A secondary alcohol + NAD+ = a ketone + NADH.
Acetaldehyde + CoA + NAD+ = acetyl-CoA + NADH.
