APases are believed to increaseorthophosphate (Pi) availability under phosphorous deficient conditions. The APase fromchickpea was purified by ethanol precipitation, followed by successive chromatographies onDEAE-Cellulose and Sephadex G-150. The enzyme was purified 73-folds. The optimumtemperature and pH for enzyme activity were 50 °C and 5.5, respectively. All metal saltsexcept ZnCl2 and HgCl2 were tolerated and did not adversely affect APase activity. Thepurified enzyme had a lower Km (0.25 mM) and higher Vmax (9 mM) for PNPP. The APase hadbroad substrate specificity with PNPP and natural substrates.}, number={4}, journal={Research in Plant Biology}, author={Kaur, Parminder and Sharma, Arun Dev and Rakhra, Gurmeen}, year={2011}, month={Oct.} }
