Abstract
Abstract A procedure has been developed for the radiochemical synthesis of [ 14 C]hydroxyguanidine by reaction of [ 14 C]cyanamide and hydroxylamine. A colorimetric assay for hydroxyguanidine which can be used for its assay in biological systems has been developed. This assay was employed to evaluate a novel enzyme isolated from terminal instar larvae of the tobacco budworm, Heliothis virescens [Noctuidae], which catalyzes an NADH-dependent reduction of hydroxyguanidine to guanidine.
