Is the oxygen atom of carbon monoxide coordinated to the copper of hemocyanin?
The carbon monoxide binding site of hemocyanins was studied by comparing the isotope shift of the CO-stretching frequencies in CO-hemocyanins with that of carbon monoxide diethylenetriaminecopper(I)tetraphenylboron in which the carbon atom of CO is coordinated to the copper. Coordination by the carbon atom of CO-hemocyanin is suggested.
