chromatography: Alkaline inorganic pyrophosphatase activity was eluted as a single peak from a DEAE cellulose
column. The leading and trailing 8 ml fraction represented 4.5 and 9.1 per cent
of the activity in the single peak fraction respectively (Table 1).
||umole Pi/mg Protein means umole Pi/mg Pyrophosphatase. The behaviour of corn alkaline inorganic pyrophosphatase on (NH4)2S04 fractionation
resembled human erythrocyte pyrophosphatase in that the bulk of the enzyme was recovered
in the 0.35-0.53 g/ml starting volume fraction. Corn alkaline inorganic pyrophosphatase
differed markedly however, from potato pyrophosphatase where 65 per cent was recovered
in the 0.224-0.448 g/ml starting volume fraction.
