• The level of alkaline inorganic pyrophosphatase (EC 3.6.1.1) in different plant leaves varies to a great extent. Out of twenty two families comprising of fifty one species of plant leaves studied, a very high level of activity was found in leaves of Amarantus blitum and Amarantus gangeticus, which belong to the Amarantaceae family. A possible role of this enzyme in the C4 pathway of photosynthesis has been discussed. The purified enzyme from the leaf of Amarantus blitum was found to have optimum pH at 9.0, with magnesium being an absolute requirement. Excess substrate inhibits the enzyme activity.
