title: Membrane-bound nucleotidase of Bacillus cereus.
abstract: A membrane-bound nucleotidase of Bacillus cereus T was solubilized by digestion with trypsin and subsequently purified more than 300-fold. The purified nucleotidase was most active on ribonucleoside 5'-monophosphates and was slightly less active (40 to 60%) on deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates. In addition to hydrolytic activity, the nucleotidase preparation possessed phosphotransferase activity by which phosphate is transferred from a phosphate donor to the 5' position of nucleosides.
