Na2S is known to support anoxygenic photosynthesis in some strains of cyanobacteria and to stimulate H2 production in N2 fixing filaments of Nostoc muscorum. We have shown electron transfer between Na2S and Photosystem I to be dependent on cytochrome b559 which was detected only in vegetative cells. An electron mediator was required to support Na2S driven nitrogenase activity in isolated heterocysts. Na2S was also found to deplete the ATP pool, probably by inhibiting electron transfer from Photosystem I.
已知硫化钠能支持某些蓝藻菌株进行不产氧光合作用，并刺激念珠藻固氮丝中的氢气产生。我们已经表明，硫化钠与光系统I之间的电子转移依赖于仅在营养细胞中检测到的细胞色素b559。在分离的异形胞中，需要一种电子介质来支持由硫化钠驱动的固氮酶活性。还发现硫化钠可能通过抑制来自光系统I的电子转移来消耗ATP库。
