title: Free tryptophan pool and tryptophan biosynthetic enzymes in Saccharomyces cerevisiae.
abstract: The free tryptophan pool and the levels of two enzymes of tryptophan biosynthesis (anthranilate synthase and indoleglycerolphosphate synthase)have been determined in a wild type strain of Saccharomyces cerevisiae and in mutants with altered regulatory properties.
