RESUMO

Membrane preparation (sedimenting between 13,000g and 80,000g) of germinating radish seeds (Raphanus sativus L.) was active in hydrolyzing ATP and, to a lesser extent, a variety of other phosphorylated compounds. Dicyclohexylcarbodiimide (DCCD) and diethylstilbestrol significantly inhibited the ATPase activity (40%) while their effect on hydrolysis of other phosphorylated compounds was much less.
