Redox, haem and CO in enzymatic catalysis and regulation
(Portland Press, 2012-06)The present paper describes general principles of redox catalysis and redox regulation in two diverse systems. The first is microbial metabolism of CO by the Wood–Ljungdahl pathway, which involves the conversion of CO or ... -
Redox-active ligands and conducting polymers in the electrochemical control of reactivity
(Massachusetts Institute of Technology, 1995) -
Redox-active materials for electrochemically-mediated separations
(Massachusetts Institute of Technology, 2021-09)Separation processes are ubiquitously employed for purification purposes in chemical production, as well as potable water generation and environmental remediation. The rising intensity of global issues such as the growing ... -
Redox-Controlled Ammonium Storage and Overturn in Ediacaran Oceans
(Frontiers Media SA, 2021)<jats:p>As a key nutrient, nitrogen can limit primary productivity and carbon cycle dynamics, but also evolutionary progress. Given strong redox-dependency of its molecular speciation, environmental conditions can control ... -
Redox-dependent rearrangements of the NiFeS cluster of carbon monoxide dehydrogenase
(eLife Sciences Publications, Ltd, 2018-10)The C-cluster of the enzyme carbon monoxide dehydrogenase (CODH) is a structurally distinctive Ni-Fe-S cluster employed to catalyze the reduction of CO 2 to CO as part of the Wood-Ljungdahl carbon fixation pathway. Using ... -
Redox-electrolytes for non-flow electrochemical energy storage: a critical review and best practice
(Elsevier BV, 2019)© 2018 The Author(s) Over recent decades, a new type of electric energy storage system has emerged with the principle that the electric charge can be stored not only at the interface between the electrode and the electrolyte ... -
Redox-informed models of global biogeochemical cycles
(Springer Science and Business Media LLC, 2020)Microbial activity mediates the fluxes of greenhouse gases. However, in the global models of the marine and terrestrial biospheres used for climate change projections, typically only photosynthetic microbial activity is ... -

Redox-Linked Changes to the Hydrogen-Bonding Network of Ribonucleotide Reductase β2
(American Chemical Society (ACS), 2013-04)Ribonucleotide reductase (RNR) catalyzes conversion of nucleoside diphosphates (NDPs) to 2′-deoxynucleotides, a critical step in DNA replication and repair in all organisms. Class-Ia RNRs, found in aerobic bacteria and all ... -
Redox-Linked Structural Changes in Ribonucleotide Reductase
(American Chemical Society (ACS), 2009-05)Ribonucleotide reductase (RNR) catalyzes the reduction of ribonucleotides to deoxyribonucleotides. Class I RNRs are composed of two homodimeric proteins, α2 and β2. The class Ia E. coli β2 contains dinuclear, antiferromagnetically ... -
Redox-responsive branched-bottlebrush polymers for in vivo MRI and fluorescence imaging
(Nature Publishing Group, 2014-11)Stimuli-responsive multimodality imaging agents have broad potential in medical diagnostics. Herein, we report the development of a new class of branched-bottlebrush polymer dual-modality organic radical contrast ... -
Redox-responsive interleukin-2 nanogel specifically and safely promotes the proliferation and memory precursor differentiation of tumor-reactive T-cells
(Royal Society of Chemistry (RSC), 2019-04)Interleukin-2 (IL-2) is a potent T-cell mitogen that can adjuvant anti-cancer adoptive T-cell transfer (ACT) immunotherapy by promoting T-cell engraftment. However, the clinical applications of IL-2 in combination with ACT ... -
Redox-responsive polymers for the reversible extraction of butanol from water
(Massachusetts Institute of Technology, 2011)Over the past few decades, increase in the demand for low molecular weight alcohols, like ethanol and butanol, for use as a biofuel has provided a new impetus to their production by the fermentation of polysaccharides, and ... -
Redrawing the boundaries: planning and governance of a marine protected area—the case of the Exuma Cays Land and Sea Park
(Springer-Verlag, 2017-02)Marine Protected Areas (MPAs) shield ocean environments from hazardous human activities, including the extraction of marine resources and excessive urban development. Delimitation, zoning and governance structures are some ... -
Redrawing the Map of Great Britain from a Network of Human Interactions
(Public Library of Science, 2010-12)Do regional boundaries defined by governments respect the more natural ways that people interact across space? This paper proposes a novel, fine-grained approach to regional delineation, based on analyzing networks of ... -
Redressing architecture : the architecture of a fashion work/shop
(Massachusetts Institute of Technology, 2002)At this moment in the twentieth century the discussions about architecture and fashion have suddenly become "in fashion". To many the topic seems suddenly timely or trendy, but unlike theories comparing the artificial ... -
Redshift Evolution of the Fundamental Plane Relation in the IllustrisTNG Simulation
© 2020 The Author(s). We investigate the Fundamental Plane (FP) evolution of early-type galaxies in the IllustrisTNG- 100 simulation (TNG100) from redshift z = 0 to z = 2. We find that a tight plane relation already exists ... -
