beta-N-acetyl-D-glucosaminidase activity of oral nutritionally variant streptococci.
The ability of nutritionally variant streptococci from the oral cavity to produce beta-N-acetyl-D-glucosaminidase (NAGase) activity was studied. Of the three biotypes analyzed, the strains belonging to biotype III were all shown to produce detectable amounts of both cell-associated and excreted NAGase activity; some strains, but not all of biotype II, were also good NAGase producers, whilst strains of biotype I were not. NVS may contribute to the production of NAGase activity found in human saliva.
