Sažetak

Treatment of peptidoglycan monomer (1) from Brevibacterium
divaricatum with either sodium hydroxide solutions or a strong
anion exchanger led to cleavage of the C-3 Iinkage in the N-acetylmuramoyl residue to give the corresponding n-lactoylpentapeptide
and the saturated disaccharide, chitobiose. Treatment with weakly basic exchangers left 1 unchanged. The results indicate that, provided the pH value of the reaction mixture is high enough, cleavage of 1 proceeds by the same mechanism irrespective of the counter-cation used.
