Ala-Glu-Lys-Ala-Ala

Application

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.

Biochem/physiol Actions

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.

An affinity support was designed to facilitate the isolation and purification of glycopeptide antibiotics by mimicking their known affinity for the bacterial cell wall. Members of this class of antibiotics inhibit peptidoglycan biosynthesis by specifically binding to pentapeptide precursors terminating

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])
