By using two-dimensional electrophoresis, five putative soluble nif gene products were identified, and the regulation of nif gene expression in Rhodopseudomonas capsulata was investigated. Expression of nif was repressed by ammonia and atmospheric concentrations of oxygen. Deprivation of molybdenum caused an interesting pattern of partial repression of nif gene expression that was not relieved by tungsten. These results are discussed in relation to the better understood system of nif regulation in Klebsiella pneumoniae.
通过二维电泳，鉴定出了五种假定的可溶性固氮基因产物，并对荚膜红假单胞菌中固氮基因表达的调控进行了研究。固氮基因的表达受到氨和大气氧浓度的抑制。钼的缺乏导致了一种有趣的固氮基因表达部分抑制模式，这种抑制不能被钨解除。结合肺炎克雷伯菌中研究得更透彻的固氮调控系统对这些结果进行了讨论。
