This investigates the occurrence of PZ-peptidase activities in Streptococcus sanguis and other oral bacteria. The strains of both Streptococcus mutans and Lactobacilli showed low levels of activity (0-0.5 unit/mg protein for S. mutans). As compared with the enzyme activities of other bacteria, a moderate range of activity was produced by the strains of Streptococcus mitis and Streptoccus salivarius. Actinomyces strains, like those of S. sanguis, produced a varying amount of activity (0-9.8 unit/mg protein)
