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.
Other Notes

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
