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.

We have determined the structure of n-butylisocyanide-bound Rhodobacter capsulatus cytochrome c'. This is the first example of a ligand-bound structure of a class IIa cytochrome c. Compared with the structure of native cytochrome c', there are significant conformational changes of

Alkyl-isocyanides are able to bind to both ferric and ferrous iron of the heme in cytochrome P450, and the resulting complexes exhibit characteristic optical absorption spectra. While the ferric complex gives a single Soret band at 430 nm, the ferrous

The linkage between the proximal histidines and the proximal polypeptide in normal adult human hemoglobin (Hb A) has been proposed to play a major role in transmitting allosteric effects between oxygen binding sites [Perutz, M. F. (1970) Nature 228, 726-734].

An 1H-NMR study of ferric cytochrome P450cam in different paramagnetic states was performed. Assignment of three heme methyl resonances of the isocyanide adduct of cytochrome P450 in the ferric low-spin state was recently performed using electron exchange in the presence

Heme-external ligand interactions of P-450nor were examined spectrophotometrically and compared with those of other P-450s. Most nitrogenous ligands induced type II spectral changes on binding to ferric P-450nor, as did other P-450s. In contrast with other P-450s, 2-methylpyridine and 1-butanol
