Application

Butyl isocyanide was used to study the crystal structure of carbon monoxide dehydrogenases-II isolated from Carboxydothermus hydrogenoformans. It was used to probe the mechanism of NO activation of the hemoprotein soluble guanylate cyclase. .

Biochem/physiol Actions

Butyl isocyanide forms complex with ferric and ferrous iron of the heme in cytochrome P450.

Thr-303 to Lys-mutated P-450 2E1, as well as Thr-301 to Lys-mutated P-450 2C2, had absorption spectra characteristic of a nitrogenous ligand-bound form of P-450, such as the pyridine complex of P-450 2E1; (i) in the ferric state, the red-shifted Soret

Alkylisocyanide adducts of microsomal P450 exist in two interconvertible forms, each giving the Soret maximum around 430 or 455 nm. This is demonstrated with a rabbit liver P450 2B4. Resonance Raman spectra of the 430- and 455-nm forms were examined
