The tetrahydrobiopterin radical with high- and low-spin heme in neuronal nitric oxide synthase -- a new indicator of the extent of NOS coupling

Reaction intermediates trapped during the single-turnover reaction of the neuronal ferrous nitric oxide synthase oxygenase domain (Fe(II)nNOS(OX)) show four EPR spectra of free radicals. Fully-coupled nNOS(OX) with cofactor (tetrahydrobiopterin, BH(4)) and substrate (l-arginine) forms the typical BH...
