Fe Protein: MgATP Induced Conformational Change and Reduction to an all Ferrous Stateified three regions of the polypeptide, switch I, switch II and the highly conserved region that includes M156 and A157, as being important for this conformational change. An A157S Fe protein variant binds MgATP but is unable to undergo the conformational change and is inactive (N. Gavini, B.K. Burg打折 发表于 2025-3-27 11:24:33

The Fe-Only Nitrogenase from ,: 1. Catalytic and EPR-Spectroscopic Properties of the FeFe Proteinnase (Fe nitrogenase) from a . mutant strain (Δ., Δ.; provided by Prof. Dr. W. Klipp, Universität Bochum) has recently been developed (Schneider et al., 1994; Schneider et al., 1997). Based on this procedure, at Fe protein: FeFe protein molar ratios of approximately 40:1, the following, remarkably h高脚酒杯 发表于 2025-3-28 09:18:15
The Fe-Only Nitrogenase From ,: 2. The FeFe Protein Metal Centers Probed by EXAFS and Mössbauer Specion procedure yielding highly active protein components (FeFe protein and Fe protein) has recently been established. The biochemical and EPR spectroscopic properties of this enzyme have been extensively studied (Schneider . this volume). We report here the first spectroscopic evidence for a high degGOAD 发表于 2025-3-28 11:55:20
The Nitrogen Cycle Sustained by Prokaryotes: Reversing Dinitrogen Fixationion, nitrification, nitrate assimilation, ammonification, and denitrification (Fig. 1). A new reaction is now being studied by which nitrate is reduced to N. at the expense of oxidation of ammonia. The process has been termed . for .aerobic .onium oxidation (Mulder et al. 1995).
