Periplasmic oligopeptide-binding protein OppA

UniProtKB accession:  P23843

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Part of the ABC transporter complex OppABCDF involved in the uptake of oligopeptides (PubMed:2187863). Plays an important nutritional role (Probable). Binds peptides containing from two to five amino acid residues (PubMed:21983341, PubMed:3536860). Displays a preference for tripeptides and tetrapeptides over dipeptides and pentapeptides, for peptides composed of L-amino acids and for positively charged peptides (PubMed:21983341, PubMed:3536860). Cannot bind the cell wall peptide L-Ala-D-Gly-gamma-meso-diaminopimelic acid (PubMed:21705338).
