Saccharomyces cerevisiae cho1/pss mutants, which are severely impaired in phosphatidylserine (PS) synthesis, do not have detectable amounts of PS in their lipid fractions. Their derivatives with mutations that cause defects in tryptophan synthesis grew poorly in a medium containing 5 micrograms/ml of L-tryptophan, a concentration that met the requirements of tryptophanauxotrophic CHO1/
PSS
strains. The rates of tryptophan uptake of trp1 cho1/pss mutants were low at low tryptophan concentrations. This defect in the use of tryptophan was restored either by expression of CHO1/
PSS
or by introduction of a gene encoding tryptophan transporter,
TAT1
or TAT2. These results indicate that PS synthesis is required for the maximal tryptophan-transporting activity of S. cerevisiae at low tryptophan concentrations.
