Microbial alcohol production from waste gases could enable sustainable carbon cycling. Now, the tungsten-dependent aldehyde:ferredoxin oxidoreductase from the gas-converting bacterium Clostridium autoethanogenum has been biochemically and structurally characterized. This monomeric enzyme is responsible for acetate reduction to acetaldehyde, the key step of ethanol production in this industrial microorganism.
