Abstract
The N2 fixing bacteria Klebsiella pneumoniae, Azospirillum brasilense, Rhodopseudomonas sphaeroides and Rhodospirillum rubrum, but not Azotobacter vinelandii accumulate the glutamine analogue methionine sulfoximine in the cell. In the accumulating cells methionine sulfoximine inhibits ammonium transport. Accumulation and inhibition are prevented by glutamine.
摘要
固氮细菌肺炎克雷伯氏菌、巴西固氮螺菌、球形红假单胞菌和深红红螺菌（但维涅兰德固氮菌不包括在内）会在细胞内积累谷氨酰胺类似物甲硫氨酸亚砜亚胺。在积累了甲硫氨酸亚砜亚胺的细胞中，它会抑制铵的转运。谷氨酰胺可阻止这种积累和抑制作用。
