Abstract
Okadaic acid and microcystin (but not the inactive methyl esters of these toxins) prevented the rapid light-induced activation of nitrate reductase (NR) in intact spinach leaves. In vitro, nitrate reductase was inactivated by a protein kinase and activated by PP2A. The role of reversible protein phosphorylation in regulation of light-coupled cytoplasmic metabolism is discussed.
