The Active Species of “CO2” Formed by Carbon Monoxide Dehydrogenase from Peptostreptococcus productus

Abstract

Carbon monoxide dehydrogenase of anaerobic bacteria catalyzes the reversible conversion of CO to “CO2”. With the enzyme from Peptostreptococcus productus it is shown that CO2 rather than HCO3_ (H2CO3) is the active species of “CO2” formed by this dehydrogenase. © 1989, Walter de Gruyter.
