Description
The acetyl-DL-glutamic acid and the chloroacetyl-DL-valine were prepared and asymmetrically hydrolyzed by the acylase obtained from several strains of mold which were known to pro-duce sufficient activity in the preceding study, and by the enzyme prepared from the Taka-dias-tase.<br> The effect of pH on the enzyme activity and the hydrolytic rates of acetyl-DL-glutanmic acid with the enzyme of A. tamarii, A. oryzae, A. flavus, P. vinaceous, P. oxalicum var. pectinoporum nov. and P. viridicatum were measured.<br> A. tamarii and P. vinaceous produced the greatest yields of the acylase.<br> An, active acylase was prepared by fractionation of water extract of culture medium with (NH4)2SO4 and acetone.<br> The active enzyme of 0.11_??_0.2g of solid matter were sufficient to hydrolyze 10g of acetyl-DL-glutamic acid.<br> The research was partly studied by one of the authors (K. MICHI) under Dr. WILLIUM C. ROSE of the University of Illinois U.S. A. during the session 1951_??_1952 under a grant from the American Association of University Women.<br> The author wishes to thank Dr. ROSE for his kind suggestions and fbr his generousity in making the facilities of his laboratory available.
