The highly purified exo-β-N-acetylglucosaminidase (β-2-acetamido-2-deoxy-d-glucoside acetamidodeoxyglucohydrolase (EC of Bacillus subtilis B has a pH Optimum of 5.9 and is most stable at 8.5. Its isoelectric point appears to be pH 3.8 and it has a mol. wt of about 75 000. The results of studies on its ability to attack a wide range of synthetic and natural substrates are given and kinetic data for the hydrolysis of a number of these reported. The Km and V values for p-nitrophenyl-2… CONTINUE READING
