摘要：

Nitrate and nitrite reciprocally inhibited the utilization of each other in the unicellular cyanobacterium Anacystis nidulans. Nitrate hampered active nitrite uptake both in wild-type cells lacking active nitrate reductase and in a nitrate reductase-defective mutant. Nitrate uptake in a nitrite reductase-defective mutant was inhibited by nitrite. The competitive interaction between nitrate and nitrite utilization in A. nidulans seems to take place at the level of substrate transport into the cell.
