Abstract
Synthetic peptides corresponding to portions of group B streptococcal peptidoglycan were used to show that the endopeptidase activity of bacteriophage B30 lysin cleaves between d -Ala in the stem peptide and l -Ala in the cross bridge and that the minimal peptide sequence cleaved is dl -γ-Glu-Lys- d -Ala-Ala-Ala. The only glycosidase activity present is that of N -acetyl-β- d -muramidase.Keywords
