some mutants of Ptr2 that are dysfunctional in dipeptide uptake were still competent to transport BlaS. Mouse-derived oligopeptide transporter PepT1 conferred BlaS sensitivity in the S. cerevisiae ptr2 mutant
Title: Critical role of the proton-dependent oligopeptide transporter (POT) in the cellular uptake of the peptidyl nucleoside antibiotic, blasticidin S.

Ptr2 mutants of the peptide-binding site exhibited severe defects in peptide import and were subject to Rsp5-dependent degradation suggesting that Ptr2 undergoes quality control that renders Ptr2 subject to efficient ubiquitination and degradation.
Title: Functional implications and ubiquitin-dependent degradation of the peptide transporter Ptr2 in Saccharomyces cerevisiae.

The substrate multispecificity of PTR2 indicates that it has an important role in the preferential uptake of vital amino acids.
Title: Analysing the substrate multispecificity of a proton-coupled oligopeptide transporter using a dipeptide library.

These studies highlight the complementary activities of two dipeptide transport systems under different regulatory controls in common laboratory yeast strains.
Title: Differential regulation and substrate preferences in two peptide transporters of Saccharomyces cerevisiae.
