Resonance Raman spectroscopy has been used to investigate the function and properties of the iron-sulfur cluster in Escherichia coli endonuclease III. Resonance Raman spectra in the Fe-S stretching region are indicative of a [4Fe-4S]2+ cluster with complete cysteinyl sulfur coordination, and vibrational assignments are made by analogy with bacterial ferredoxins. Minor changes in the vibrational frequencies of the modes primarily involving Fe-S(Cys) stretching accompany the binding of the… CONTINUE READING
