S K-edge XAS and DFT Calculations on SAM Dependent Pyruvate Formate-Lyase Activating Enzyme: Nature of Interaction between the Fe(4)S(4) Cluster and SAM and its Role in Reactivity

S K-edge X-ray absorption spectroscopy on the resting oxidized and the S-adenosyl-L-methionine (SAM) bound forms of pyruvate formate-lyase activating enzyme are reported. The data show an increase in pre-edge intensity which is due to additional contributions from sulfide and thiolate of the Fe(4)S(...
