After the sonic rupture of Streptococcus mutans cells, two fractions were obtained. The soluble cell contents hydrolyzed casein but not porcine gastric glycoprotein. The cell-debris fraction showed proteolytic activity on both casein and gastric glycoprotein. Glycoprotein hydrolase activity also was demonstrated in the medium from which the cells were harvested.
