Abstract
Membrane-associated phosphatidylinositol kinase (ATP:phosphatidylinositol 4-phosphotransferase, EC 2.7.1.67) was partially purified 93-fold from Saccharomyces cerevisiae. Activity was dependent on magnesium ions (10 mM) and the optimum pH was 8.5. The apparent Km values for ATP and phosphatidylinositol were 0.21 mM and 71 microM, respectively. Activity was stimulated by sodium cholate and inhibited by sodium, potassium, lithium, and fluoride ions.Entities:
