Research Abstract |
The biosynthesis of Fe-S clusters is a highly regulated process involving several proteins. To investigate the molecular basis of the Fe-S cluster biosynthesis pathway, we carried out the structural analysis of the holo form of chloroplast CnfU. Curve-fitting analysis of EXAFS indicated that the coordination environment of the [2Fe-2S] cluster on crystalline CnfU has a different environment from the environment at solution holo-CnfU. The structure of holo-CnfU supports a model in which CnfU has suitable structural feature for Fe-S cluster formation and transfer under an elevated oxygen environment.
