Action comparée de trois lysozymes d'origine différente sur des substrats glycopeptidiques isolés de Microcossus lysodeikticus

摘要: Resume Two soluble purified glycopeptidic substrates of lysozyme were isolated and analyzed. Hen's egg-white lysozyme, duck's human milk hydrolyze these substrates: this fact seems to confirm that the three lysozymes which are analogous but not identical substances β-glucosaminidases ( N -acetylmuramide glycanohydrolases). Their kinetics action are, however, different. Duck's is most active one: chromatographic experiments amino acid analyses have shown last enzyme has a higher content basic acids than others. These seem play an important role in biological activity lysozymes.
