Abstract

The rate of glycylleucine uptake by Group N streptococci varied widely. One strain of did not transport the dipeptide or utilize tripeptides. In peptide-utilizing strains, amino acid, dipeptide and tripeptide transport were distinct, although dipeptides inhibited tripeptide utilization. Specificity determinants for peptide transport and utilization were similar to those reported in Gram-negative bacteria. Peptide utilization in was not completely dependent on the transport of intact peptides.
