A MoFe protein (ΔnifE Av1) with a purity of ~80% was purified from a nifE-deleted mutant of Azotobacter vinelandii DJ35. Compared with MoFe protein purified from wild-type strain OP (OP Av1), ΔnifE Av1 had the same...
In recent years, the investigation of biological nitrogen fixation and analogy to biological nitrogen fixation are a very active field and the researches for micro-surroundings of active centre in metalloenzyme have r...
Ⅰ. INTRODUCTION With the development of studies on biological nitrogen fixation, the investigation on the micro-circumstances of active centers in metalloenzyme has reached the
