Abstract
We report the photobiochemical production of carbon monoxide by a terminal ba3-cytochrome c oxidase from T. thermophilus HB8. FTIR and time-resolved step-scan FTIR spectroscopies were combined to probe this process and also monitor the concomitant binding of the produced gas to other intact ba3 molecules forming the ba3-CO complex. The activation of this mechanism by ba3-oxidase under visible excitation raises the question as to whether such a mechanism is physiologically relevant to the extreme environment in which it operates.
