Amino Acid Sequence 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. |
