ala-D-G-glu-lys-D-ala-D-ala

Description:

The chemical substance known as "ala-D-G-glu-lys-D-ala-D-ala," with the CAS number 2614-55-3, is a peptide that consists of a sequence of amino acids, specifically incorporating both L- and D-forms of amino acids. This compound is a derivative of the peptide structure commonly found in bacterial cell walls, particularly in peptidoglycan, which provides structural integrity to the cell. The presence of D-amino acids is significant as they contribute to the resistance of the peptide to enzymatic degradation by proteases, which typically target L-amino acids. The characteristics of this peptide include its potential role in antibiotic resistance mechanisms, as it can mimic natural substrates for bacterial enzymes. Additionally, it may exhibit antimicrobial properties and could be of interest in pharmaceutical research for developing new antibiotics or understanding bacterial cell wall synthesis. Its stability, solubility, and biological activity are influenced by the specific arrangement and composition of the amino acids within the peptide chain.

Teicoplanin is an amide-linked glycopeptide antibiotic that binds to the bacterial cell wall. It is used for the treatment of infections caused by staphylococci and p. aeruginosa, which are resistant to other antibiotics. The drug binds to a specific site on the bacterial cell wall, forming a coordination complex with the peptidoglycan layer and making it easier for water molecules to penetrate the cell wall. This leads to increased rates of cell death by osmosis. Teicoplanin enhances the activity of other antibiotics against Gram-positive bacteria by preventing their binding to penicillin-binding proteins in the bacterial cell walls.
