[Activators of phospholipase D].

The activation of phospholipase D from cotton seeds by diethyl ester, sodium dodecyl sulphate and silica gel during egg lecithin hydrolysis was investigated. In the presence of silica gel the enzymic reaction developed without calcium ions. The data were accumulated indicating that the main characteristics of phospholipase D obtained from the in vitro study of the enzymic hydrolysis of phospholipids depended at large on the activator applied.
