Two disaccharides have previously been obtained in high yield from the cell wall of S. aureus by the use of hydrolytic enzymes. Disaccharide 1 is N-acetylglucosaminyl-N-acetylmuramic acid and disaccharide 2 is N-acetylglucosaminyl-N,Ogr;-diacetylmuramic acid. After hydrolysis of disaccharide 2 with β-acetylglucosaminidase, N,O-diacetylmuramic acid was prepd. Data obtained from periodate oxidn. of these compds. coupled with their susceptibility to β-acetylglucosaminidase indicate that both disaccharides are β-1,4-linked and that the O-acetyl group of disaccharide 2 is on the 6-position of N-acetylmuramic acid. The high reducing power and pos. Morgan-Elson reaction of the disaccharides are due to their unusual susceptibility to hydrolysis at alk. pH. These and other anomalous properties of the compds. are discussed. [on SciFinder(R)] [less ▲]

Staphylolytic Enzyme from Chalaropsis: Mechanism of Action

in Science (1964), 146

The staphylolytic enzyme recently isolated from cultures of a Chalaropsis species by Hash is shown to be an acetylmurainidase that cleaves all the glycosidic linkages of N-acetylmuramic acid and N,O ... [more ▼]

The staphylolytic enzyme recently isolated from cultures of a Chalaropsis species by Hash is shown to be an acetylmurainidase that cleaves all the glycosidic linkages of N-acetylmuramic acid and N,O-diacetylmuramic acid in the cell wall of Staphylococcus aureus strain Copenhagen. It is similar in specificity to the "32 enzyme" from Streptomyces albus but it differs from egg-white lysozyme whose activity is inhibited by the presence of O-acetyl groups. [less ▲]
