[Properties of phosphoprotein phosphatase from the rat liver].
Prosphoproteid phosphatase, an enzyme highly specific to lysyl-tRNA-synthetase and proteins of the high-molecular-multienzymic complex of aminoacyl-tRNA-synthetases, was isolated from the rat liver. The data of electrophoresis in 4-30% PAAG with the presence of DS-Na have shown that phosphoproteid phosphatase is homogeneous and its molecular mass is 56 kDa. The isolated phosphoproteid phosphatase is activated by 2.5 mM Mg2+, Mn2+ and is inhibited by ions of univalent metals ions--200 mM Na+, 5 mM K+ as well as by 1 mM ATP, ADP, AMP.
