Protein
Periplasmic murein peptide-binding protein
Organism
Escherichia coli (strain K12)
Function
Essential for the uptake of the murein peptide L-alanyl-gamma-D-glutamyl-meso-diaminopimelate. Also transports some alpha-linked peptides such as Pro-Phe-Lys with low affinity. The transport is effected by the oligopeptide permease system.
Similarity
Belongs to the bacterial solute-binding protein 5 family.
