Abstract
Activity and properties of two phosphohydrolases, nucleoside diphosphatase (NDPase) and 5′-nucleotidase, were assayed in subcellular fractions of turbellaria Phagocata sibirica Sabussov (Turbellaria, Planariidae). The highest activity of N D Pase was observed in microsomes while that of 5′-nucleotidase in mitochondria and cytosolic fractions (12 000 and 105 000 g). The correlation between the rates of the relevant enzymatic reactions and concentrations of substrates and metal ions as well as the impact of various effectors and divalent cations (Mg2+, Mn2+, Ca2+, Zn2+, Cu2+) on phosphohydrolase activities were studied.
