A simple method for preparation of snake venom phosphodiesterase almost free from 5'-nucleotidase. 1975

T Tatsuki, and S Iwanaga, and T Suzuki

A simple method, involving NAD+-Sepharose chromatography, was developed for the preparation of snake venom phosphodiesterase (EC 3.1.4.1) almost free from 5'-Nucleotidase (EC 3.1.3.5). Using an NAD+-Sepharose 4B column, phosphodiesterase was eluted in the unadsorbed fraction, whereas 5'nucleotidase was strongly adsorbed. The latter enzyme was desorbed when 0.2 M sodium bicarbonate buffer containing 1mM beta-NADH was used as a solvent. The affinity column could be used at least four times without any decrease of potency, and the method was applicable for the preparation of phosphodiesterase from the venoms of rattlesnake (Crotalus adamanteus) and Japanese mamushi (Agkistrodan halys blomhoffi).

D009243	NAD	A coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH).
