Abstract/Summary:
The effect of ozone (O;Ozone may accelerate the decline in rubisco by increasing enzyme acceptability to proteases. To test this hypothesis, rubisco was purified from Norland potato foliage and the enzyme exposed to O;Oxidant treatment reduced the quantity of rubisco an average of 15%. Addition of protease further reduced the quantity by another 30% after O...
