Abstract

Resonance Raman spectroscopy (RR) a technique that enables iron ligand stretching modes to be identified to characterize the NO-bound complex of cytochrome cbb(sub 3) oxidase is described. The existence of a five-coordinate heme b(sub 3) Fe(super 2+)-NO complex was found.

Abstract

Examines the influence of the heme Fe-CO complex of cytochrome cbb[sub 3]-CO at ambient temperature formation on the decay of the transient Cu[sub B]-CO complex. Use of time-resolved fourier transform infrared spectroscopy; Catalyzation of molecular oxygen reduction by the complex; Importance of photodynamics of cbb[sub 3]-CO for elucidating the mechanisms for legal entry/exit in heme-cooper oxidase.
