摘要：
Mo and Fe K-edge EXAFS analysis of NifQ shows the presence of a [MoFe3S4] cluster and a second independent Mo environment that includes Mo-O bonds and Mo-S bonds. Both environments are relevant to FeMo-co biosynthesis and may represent different stages of Mo biochemical transformations catalyzed by NifQ.
