Abstract
A method for the generation of phenylthiocarbamyl (PTC) amino acids from phenylthiohydantoin (PTH) or anilinothiozolinone (ATZ) amino acids. The method involves a base-catalyzed ring opening of the PTH or ATZ in the presence of a reducing agent. The method affords an alternative to the established aqueous acid conversion reaction of the Edman degradation in which ATZ and PTC amino acids are converted to the PTH amino acid. A further method is described for the generation of reactive ATZ amino acids from PTH amino acids. These methods facilitate the analysis of protein at low molar amounts by allowing the synthesis of amino acid derivatives which can be analyzed in quantities which are much lower than those required for conventional PTH amino acid analysis.
