Inhibition of HCO(3)(−) Binding to Photosystem II by Atrazine at a Low-Affinity Herbicide Binding Site

In maize chloroplasts, the ratio of HCO(3)(−) (anion) binding sites to high-affinity atrazine binding sites is unity. In the dark, atrazine noncompetitively inhibits the binding of half of the HCO(3)(−) to the photosystem II (PSII) complexes. The inhibition of binding saturates at 5 micromolar atraz...
