1 Here we characterize the substrate multispecificity of Ptr2p, a major peptide transporter of Saccharomyces cerevisiae, using a dipeptide library. Dipeptides Ptr2p Saccharomyces cerevisiae S288C
2 The affinities (Ki) of di/tripeptides toward Ptr2p show a wide distribution range from 48 mM to 0.020 mM. di/tripeptides Ptr2p Saccharomyces cerevisiae S288C
