ABSTRACT:
A method of purifying proteases from the Herpes Simplex Virus 1 and 2 is taught. A precursor protease is cloned in a host cell and then separated from the cell culture using cation exchange chromatography. The resulting protease is subjected to autoprocessing conditions and an autolytic cleavage occurs, resulting in mature protease.
