Abstract
The effect of various nucleotides on the Fe-containing component of nitrogenase of Klebsiella pneumoniae was investigated by ultracentrifugation and thiol-group reactivity towards 5,5'-dithiobis-(2-nitrobenzoate). In the absence of Na(2)S(2)O(4), ATP and ADP produced changes in sedimentation behaviour and thiol-group reactivity consistent with association of the protein.
摘要
通过超速离心以及巯基对5,5'-二硫代双（2-硝基苯甲酸）的反应活性，研究了各种核苷酸对肺炎克雷伯菌固氮酶含铁成分的影响。在没有连二亚硫酸钠的情况下，ATP和ADP使沉降行为及巯基反应活性发生变化，这与蛋白质的缔合相一致。
