Res. , Article ASAP DOI: 10.1021/ar400149m Publication Date (Web): September 26, 2013 Copyright © 2013 American Chemical Society Abstract Mononuclear non-heme Fe (NHFe) enzymes play key roles in DNA repair, the biosynthesis of antibiotics, the response to hypoxia, cancer therapy, and many other biological processes. These enzymes catalyze a diverse range of oxidation reactions, including hydroxylation, halogenation, ring closure, desaturation, and electrophilic...

Rescuing Auxotrophic Microorganisms with Nonenzymatic Chemistry † Dr. Yunmi Lee 1 ,  Afoma Umeano 2 ,  Prof. Emily P. Balskus 2,* Article first published online: 20 SEP 2013 DOI: 10.1002/anie.201307033 Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Keywords: auxotrophy; hydroxylation; metabolism; microorganisms; protecting groups Organic chemistry to the rescue : Two unrelated nonenzymatic chemical reactions can support the growth of auxotrophic  E. coli  strains by generating essential nutrients in situ. These biocompatible reactions, which take place in the presence of the organisms and are designed to interface with cellular metabolic processes, provide a means of linking the growth of an organism to the success of a nonbiological chemical transformation.

Communication You have full text access to this content Comparison of the Reactivity of Nonheme Iron(IV)–Oxo versus Iron(IV)–Imido Complexes: Which is the Better Oxidant? † Anil Kumar Vardhaman 1 ,  Prasenjit Barman 1 ,  Suresh Kumar 2 ,  Dr. Chivukula V. Sastri 1,* ,  Dr. Devesh Kumar 2,* ,  Dr. Sam P. de Visser 3,* Article first published online: 25 SEP 2013 DOI: 10.1002/anie.201305370 Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Keywords:  C H activation; enzyme models; imido ligands; iron; sulfoxidation Which is better?  The first detailed study into a comparison of the reactivity of nonheme iron(IV)–imido versus nonheme iron(IV)-oxo intermediates with substrates is presented. The iron(IV)–imido variant reacts with sulfides five times faster than iron(IV)–oxo, whereas the reverse trend is observed for hydrogen atom abstraction. These observed trends are analyzed and explained. View...
