Second Sphere Effects on Oxygen Reduction and Peroxide Activation by Mononuclear Iron Porphyrins and Related Systems

Sarmistha Bhunia et al.

Summary: Activation and reduction of O-2 and H2O2 by synthetic and biosynthetic iron porphyrin models have been proven to be a versatile platform for evaluating second-sphere effects important in natural heme active sites. By installing different functional groups around the porphyrin ligand, several second-sphere effects have been evaluated under controlled environments, providing fundamental insights into the roles played by these weak interactions in nature.

Bioinorganic Chemistry on Electrodes: Methods to Functional Modeling

Abhijit Nayek et al.

Summary: One of the major goals of bioinorganic chemistry is to mimic the function of metalloenzymes. By utilizing heterogeneous electrochemistry and molecule design, it is possible to control both electron and proton transfer reactions. This control enables functional modeling of various important reactions and provides insights into unnatural bioinspired reactions and reorganization energy estimation.

The three-spin intermediate at the O-O cleavage and proton-pumping junction in heme-Cu oxidases

Anex Jose et al.

Summary: Heme-copper oxidases play a crucial role in cellular respiration by cleaving the oxygen-oxygen bond to form the key intermediate PM, which initiates proton pumping. Experimental evidence shows that the heme iron(IV)-oxo in PM is magnetically coupled to both a copper(II) and a cross-linked tyrosyl radical in the active site, providing new insight into the oxygen-oxygen bond cleavage and proton-pumping mechanisms.
