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.

The relationship between 7S anti-IgG and antibodies to streptococcal cell wall peptidoglycan was examined for four streptococcal Group C antisera. Homogeneous 7S anti-IgG components in these sera were isolated by means of an IgG immunoadsorbent column. For two of the

Vancomycin forms complexes with peptides terminating in d-alanyl-d-alanine that are analogous to the biosynthetic precursors of bacterial mucopeptides. The specificity of complex-formation has been studied by means of many synthetic peptides, prepared by both solid-phase and conventional methods. The following
Immunochemistry of a synthetic peptidoglycan-precursor pentapeptide.

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

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
