Nitric oxide trapping of the tyrosyl radical-chemistry and biochemistry

The quenching of the Y D tyrosyl radical in photosystem II by nitric oxide was reported to result from the formation of a weak tyrosyl radical-nitric oxide complex. This radical/radical reaction is expected to generate an electron spin resonance (ESR)-silent nitrosocyclohexadienone species that can...
