products description :
Venom exonuclease (Phosphodiesterase I) successively hydrolyzes 5'-mononucleotides from 3'-hydroxy-terminated ribo-and deoxyribo-oligonucleotides. The enzyme has been widely utilized as a tool for structural and sequence studies of nucleic acids. The enzyme has been purified with endonuclease activity being eliminated as well as 5'-nucleotidase and nonspecific monophosphatase. It is nonspecific with respect to base or sugar moieties of nucleotides. A variety of synthetic substrates are hydrolyzed. The exonuclease will not recognize nucleoside units in the syn conformation. ADP-ribosylated proteins are cleaved at the pyrophosphate linkages by venom phosphodiesterase to yield phosphoribosyl-AMP.
