D-Ala-D-Ala,

Biochem/physiol Actions

D-Ala-D-Ala, a terminus moiety of bacterial peptidoglycans, is used for affinity chromatography and binding mechanism studies of antibiotics such as teicoplanin, ristocetin, vancomycin.

D-Ala-D-Ala is found in the stem termini of peptidoglycan side-chain pentapeptide found in the cell walls of gram positive bacteria. The D-ala-d-ala stem termini is the site of interaction of glycopeptide antibiotics such as vancomycin and teicoplanin. D-ala-D-ala is a substrate used to study kinetics of UDPMurNAc-tripeptide D-alanyl-D-alanine-adding (ligase) enzyme.
