CYTOCHROME C' FROM ALCALIGENES XYLOSOXIDANS-REDUCED STRUCTURE WITH NO BOUND TO PROXIMAL SIDE OF HEME
Overview
Microbial cytochromes c' contain a 5-coordinate His-ligated heme that, forms stable adducts with nitric oxide (NO) and carbon monoxide (CO), but, not with dioxygen. We report the 1.95 and 1.35 A resolution crystal, structures of the CO- and NO-bound forms of the reduced protein from, Alcaligenes xylosoxidans. NO disrupts the His-Fe bond and binds in a novel, mode to the proximal face of the heme, giving a 5-coordinate species. In, contrast, CO binds 6-coordinate on the distal side. A second CO molecule, not bound to the heme, is located in the proximal pocket. Since the, unusual spectroscopic properties of cytochromes c' are shared by soluble, guanylate cyclase (sGC), our findings have potential implications for the, activation of sGC induced by the binding of NO or CO to the heme domain.
