An electron spin resonance study of free radical intermediates in the oxidation of indole acetic acid by horseradish peroxidase.

Year: 1986

Type: article

Abstract: The oxidation of indole-3-acetic acid by horseradish peroxidase was studied using the spin traps t-nitrosobutane and 5,5-dimethyl-1-pyrroline N-oxide to trap free radical intermediates. The major free radical metabolite of indole acetic acid was unambiguously determined by the use of indole-3-[2,2-2H2]acetic acid to be the skatole carbon-centered free radical. In the presence of oxygen, superoxide was also trapped.
