o-Fluoro-dl-phenylalanine (OFP)-resistant mutants which overproduce β-phenethyl-alcohol were isolated from a laboratory strain of Saccharomyces cerevisiae. Cells of one of the mutants accumulated tyrosine and phenylalanine 1.5–3 fold more than did wild-type cells. Its 3-deoxy-d-arabino-hepturosonate-7-phosphate (DAHP) synthase (EC 4.1.2.15), encoded by ARO4, was free from feedback inhibition by tyrosine. Genetic analysis revealed that the mutation was controlled by a single dominant gene, ARO4… CONTINUE READING
