Abstract
Di- and tripeptides shared the same transport system in S. cerevisiae. Typical rates of uptake were 1-5 nmol peptide min-1 (mg dry wt)-1; these rates were influenced by the composition and sequence of the peptide. Accumulation of intact sarcosine peptides was demonstrated. Rates of peptide uptake were essentially the same in the wild-type and in several amino acid permease-deficient mutants. These results were derived from application of 2 fluorescence methods that permit direct determination of peptide uptake.This publication has 8 references indexed in Scilit:
