Abstract
l-Methionine-dl-sulfoximine (MSX) stimulated nitrate uptake but inhibited 14CO2 fixation and O2 evolution inAnabaena doliolum. Nitrate uptake was inhibited by ammonium (NH 4+ ) in the absence of MSX, but not in the presence of MSX. Glutamine or a derivative of it appears to be the actual negative effector of nitrate utilization. In presence of nitrate, MSX-treated cells of A. doliolum evolve more O2 than do untreated cells. Our results suggest a close relation between photoassimilation of carbon and utilization of nitrogen.
