3.A.1.5.1
Oligopeptide porter (also takes up amino glycoside antibiotics such as kanamycin, streptomycin and neomycin as well as cell wall-derived peptides such as murein tripeptide). It transports substrate peptides of 2-5 amino acids with highest affinity for tripeptides. Also transports δ-aminolevulinic acid (ALA). [May be regulated by PTS Enzyme INtr-aspartokinase.] ATP-binding to OppDF may result in donation of peptide to OppBC and simultaneous release of OppA (Doeven et al., 2008).
