Protein

NADP-dependent isopropanol dehydrogenase

Gene

adh

Organism
Clostridium beijerinckii (Clostridium MP)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Alcohol dehydrogenase with a preference for medium chain secondary alcohols, such as 2-butanol and isopropanol. Has very low activity with primary alcohols, such as ethanol. Under physiological conditions, the enzyme reduces aldehydes and 2-ketones to produce secondary alcohols. Is active with acetaldehyde and propionaldehyde.2 Publications
