Rebinding of proximal histidine in the Cytochrome c' from Alcaligenes xylosoxidans acts as a molecular trap for nitric oxide

Abstract : Transient absorption spectra on cytochrome c' and their kinetics were recorded to identify the formation of 5-coordinate (5c)-NO and 5c-His hemes from 4c-heme (99% and 1% amplitudes; 7-ps and 100-ps time constants, respectively). We demonstrate that proximal histidine precludes NO rebinding at the proximal site.
