| Abstract: | Human placental alkaline phosphatase, a marker protein for some nontrophoblastic neoplasms, was found to have phosphoprotein phosphatase activity. This was demonstrated by the dephosphorylation of 32P-labeled histones, protamine, glycogen synthetase, casein, and phosvitin at various pH values. Unlike the general phosphoprotein phosphatase, the placental alkaline phosphatase does not have phosphorylase phosphatase activity. |
