Sažetak

The infrared stretching vibrations (vc0 ) of the CO-complexes
of cytochrome P450 and cytochrome P420 have been determined
from the infrared difference spectra. The CO-complexes exhibit
ir-bands at 1949 cm-1 and 1966 cm-1 with half widths of -17 cm·1
and - 20 cm·1 respectively. These results are con;ipared with the
CO-stretching frequencies of other hemoproteins and discussed with
respect to specific interactions of the CO-ligand with the protein
moiety and to the ligand trans to CO in the cytochrome.
