Application
- Binding Mode-Based Physicochemical Screening Method Using d-Ala-d-Ala Silica Gel and Chemical Modification Approach to Facilitate Discovery of New Macrolactams, Banglactams A and B, from Nonomuraea bangladeshensis K18-0086.: Describes a novel screening method employing D-Ala-D-Ala silica gel to discover new macrolactams with potential antibacterial properties. This technique aids in identifying compounds that inhibit bacterial cell wall synthesis (Kimishima et al., 2024).
Biochem/physiol Actions
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.
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.
