Oxidative transformations of coded aromatic amino acids with 4-t-butyl lodylbenzene
Abstract
A study of the action of 4-t-butyl iodylbenzene (1) on the side chains of the four coded aromatic amino acids has shown that tryptophan is transformed to kynurenine, arising from (1) in the role of an ozone equivalent, histidien to γ-formamido glutamine, by pathways similar to those delineated for histidine catabolism, tyrosine to 3,4-dihydroxy-phenylalanine quinone, and phenylalanine recovered unchanged.
