In the heterocystous cyanobacterium Anabaena variabilis, a change in nitrogenase activity and concomitant modification of dinitrogenase reductase (the Fe protein of nitrogenase) was induced either by NH4Cl at pH 10 (S. Reich and P. Böger, FEMS Microbiol. Lett. 58:81-86, 1989) or by cessation of C supply resulting from darkness, CO2 limitation, or inhibition of photosystem II activity. Modification induced by both C limitation and NH4Cl was efficiently prevented by anaerobic conditions. Under… CONTINUE READING
