Aplicación

Ala-D-γ-Glu-Lys-D-Ala-D-Ala is the pentapeptide tail of the peptidoglycan precursor UDPMurNAc-l-Ala-γ-d-Glu-l-Lys(Gly)(5)-d-Ala-d-Ala. Ala-D-γ-Glu-Lys-D-Ala-D-Ala is used to study the role of this peptide stem in peptidoglycan biosynthesis, degradation and function.

Acciones bioquímicas o fisiológicas

L-Ala-D-Glu-gamma-L-Lys-D-Ala-D-Ala, peptidoglycan pentapeptide, is the antigenic peptide determinant of peptidoglycan useful in studies of mechanisms of action of glycopeptide antibiotics.

A radioimmunoassay has been developed for the measurement of antibodies to peptidoglycan in human sera including patients with rheumatic fever and juvenile rheumatoid arthritis. The assay is based on the percentage of binding of the hapten 125I-L-Ala-gamma-d-Glu-L-Lys-D-Ala-D-Ala, the major peptide

Staphylococcus epidermidis peptidoglycans solubilized by sonication or lysozyme digestion, and synthetic peptidoglycan analogs such as HSA-carboxymethyl-Gly-L-Ala-L-Ala-D-Ala-D-Ala (HSA-pentapeptide) or L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala (pentapeptide) have been labeled with 125I and tested for their applicability in the radioactive antigen binding assay. Use of radioiodinated Staph.

The enzymatic synthesis of the complete l-alanyl(1)-l-alanine(2) side chain of the peptidoglycan precursors of Enterococcus faecalis was obtained in vitro using purified enzymes. The pathway involved alanyl-tRNA synthetase and two ligases, BppA1 and BppA2, that specifically transfer alanine from Ala-tRNA

Enterococcus faecalis BM4405-1, a susceptible derivative of the VanE-type vancomycin-resistant E. faecalis strain BM4405, was obtained after growth in the presence of novobiocin, an inhibitor of the GyrB subunit of DNA gyrase. In contrast to findings for BM4405, UDP-MurNAc-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala (pentapeptide[D-Ala])
