The Active Species of "C02" Formed by Carbon Monoxide Dehydrogenase from Peptostreptococcus productus

Abstract
Carbon monoxide dehydrogenase of anaerobic bacteria catalyzes the reversible converison of CO to "CO2". With enzyme from Peptostreptococcus productus it is shown that CO2 rather than HCO3- (H2CO3) is the active species of "CO2" formed by this dehydrogenase.
