Phosphodiesterase I
Enzymes
One unit hydrolyzes 1 µmole of p-nitrophenyl thymidine-5-phosphate per minute at pH 8.9 and 25 °C.

Activators: The enzyme has an absolute requirement for Mg2+; Philipps indicates an optimum concentration of 15 mM. Inhibitors: Reducing agents such as gluctathione, cysteine and ascorbic acid. It is completely inhibited by 5 mM EDTA while ATP, ADP and AMP are partial inhibitors. Composition: A glycoprotein which binds concanavalin A.

Phosphodiesterase I breaks phosphodiester bonds and catalyzes the hydrolysis of various nucleotide polyphosphates. Phosphodiesterase I is released from eucaryotic plasma membranes by phosphatidylinositol-specific phospholipase C.
