We previously reported the activation of adenylate cyclases from rat brain (Johnson, R. A., Awad, J. A., Jakobs, K. H., and Schultz, G., (1983) FEBS Lett. 152, 11-16) and from human platelets (Jakobs, K. H., Johnson, R. A., and Schultz, G. (1983) Biochim. Biophys. Acta 756, 369-375) by a factor derived from bovine sperm. In this report we describe the conditions for the extraction of the factor...
Isolation and properties of a phosphatidylcholine-specific phospholipase C from bull seminal plasma.
A phospholipase C which hydrolyzes [14C]phosphatidylcholine has been purified 1782-fold from 70% ammonium sulfate extract of bull seminal plasma. Purification steps included acid precipitation, chromatography on DEAE-Sephacel, concanavalin A, octyl-Sepharose 4B and Ultrogel AcA 34. The final step provided homogeneous phospholipase C as determined by polyacrylamide gel electrophoresis. The enzym...
