UNSPECIFIED (1993) REGULATION OF HILL REACTION COUPLED TO PHOTOREDUCTION OF NITRATE AND NITRITE IN ANABAENA-DOLIOLUM. [Journal Item]
Full text not available from this repository.Abstract
The photoreduction of nitrate and nitrite with water as the electron donor was observed in Anabaena doliolum. Dicyclohexyl carbodiimide, a specific inhibitor of ATPase, inhibited O2 evolution as this process involved ATP hydrolysis. Cyanide-m-chlorophenyl hydrazone, an uncoupler, abolished O2 evolution by breakdown of the active energy dependent transport of nitrate and nitrite and of the proton gradient. NH4Cl, methylamine and hydroxylamine inhibited O2 evolution by acting as bases and cleaving high energy bonds. EDTA combined with the metal ions that were required for oxygen evolution, synthesis-of photosynthetic units and photophosphorylation. This resulted in the blockage of the nitrate and nitrite photoreduction coupled to O2 evolution by preventing transfer of electrons from water and reductant for nitrate and nitrite reduction.
