Phosphodiesterase production with bis-p-nitrophenyl phosphate as a substrate by alkalophilic Bacillus No. A-40-2 increased with increasing Mn2+ concentration, showing maximum productivity at 10 mm. The enzyme production was negligible in the medium without Mn2+. The simultaneous addition of 10 mm Mn2+ and one of the several cations Mg2+, Co2+, Mo6+, and Pb2+ at suitable concentrations stimulated the enzyme production 1.8-fold at most over that with only 10 mm Mn2+. Inorganic phosphate hardly repressed the enzyme production. The enzyme was purified homogeneously. The purified enzyme had the optimum pH of 7.5 and was fairly stable from pH 7–11. The enzyme hydrolyzed 2′,3′-cyclic-nucleotides and 3′-nucleotides, but did not hydrolyze 3′,5′-cyclic-nucleotides or 5′-nucleotides, indicating it to be a 2′,3′-cyclic-nucleotide 2′-phosphodiesterase (EC 3.1.4.16). The enzyme had activity without metals, but Mg2+, Ca2+, Ba2+, and Mo6+ activated the enzyme reaction.
