Description

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

May form haziness and/or precipitate with no loss in purity.
