The enzyme activity towards arachdonic acid was highest at pH 7.5 and at temperatures between 10℃ and 20℃. The molecular weight of enzyme estimated by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS-PAGE) was 70,000 near that of the enzyme from human leukocyte (65,000-75,000)[E.Sigal et.al : J.
