Webreaction buffer containing ONPG as the substrate. Subsequent data reduction was performed using Gen5 software. In order to determine Michaelis-Menten equation values, a series of dilutions of the ONPG substrate were utilized. A 20 mM stock solution of ONPG substrate in 2X reaction buffer was prepared and dilutions from 0 to 20 mM were made
