Theoretical Modeling of Low-Energy Electronic Absorption Bands in Reduced Cobaloximes [PDF]
, 2014 The reduced Co^I states of cobaloximes are powerful nucleophiles that play an important role in the hydrogen-evolving catalytic activity of these species.

Chemistry – A European Journal, Volume 30, Issue 49, September 2, 2024.To find the structural requirements of a B12‐derivative to bind and switch the btuB riboswitch we derivatised the corrin sidechains b and e as well as the apical ligand. While modifications at the sidechains have a large impact on the riboswitch, introduction of an apical adenosyl‐ligand restores the riboswitch fold.

A bioassay for the detection of benzimidazoles reveals their presence in a range of environmental samples [PDF]
, 2014 Cobamides are a family of enzyme cofactors that include vitamin B12 (cobalamin) and are produced solely by prokaryotes. Structural variability in the lower axial ligand has been observed in cobamides produced by diverse organisms. Of the three classes of

Emission‐based sensing of cobalt (II) and vitamin B12 via a bis‐indole derivative
Luminescence, Volume 39, Issue 8, August 2024.In this study, a newly synthesized bis‐indole derivative has been successfully used in the analysis of both ionic cobalt and vitamin B12. The fluorescent bis‐indole ligand surrounds cobalt ions and acts similarly to the corrin ring in the structure of vitamin B12 in nature.

Corrins and the Acetyl-CoA Path of Autotrophic Fixation of Carbon Dioxide in Bacteria [PDF]
, 1988 Autotrophic fixation of carbon dioxide in bacteria proceedes not only via the well-known «Calvin cycle», but also via the recently established «acetyl-coenzyme A pathway», meanwhile found to be widely distributed in bacterial anaerobes.

Burning question: Rethinking organohalide degradation strategy for bioremediation applications
Microbial Biotechnology, Volume 17, Issue 8, August 2024.This review specifically focuses on the novel solution of organohalide bioremediation, proposing redox‐potential‐mediated hybrid bioprocesses tailored to the complexities of organohalide pollution. Abstract Organohalides are widespread pollutants that pose significant environmental hazards due to their high degree of halogenation and elevated redox ...

AN INVESTIGATION OF THE EFFECTS OF CORRINOID STRUCTURE ON THE METHANOGENESIS PATHWAY IN \u3ci\u3eMETHANOSARCINA BARKERI\u3c/i\u3e STRAIN \u3ci\u3eFUSARO\u3c/i\u3e [PDF]
, 2018 Methane is responsible for at least 10% of greenhouse gas emissions in the United States alone, and although not the most abundant, it is one of the most dangerously potent greenhouse gases.

Freshwater Biology, Volume 69, Issue 8, Page 1069-1083, August 2024.Abstract Evidence suggests that low cobalt (Co) may limit heterocyst frequency (HF) in filamentous diazotrophic cyanobacteria. Therefore, the effect of three Co concentrations on HF in four species in the genera Aphanizomenon and Dolichospermum was examined in N‐depleted (N was not added) culture.

Angewandte Chemie, Volume 136, Issue 31, July 29, 2024.Der bifunktionale CO‐Dehydrogenase (CODH)/Acetyl‐CoA‐Synthase (ACS)‐Komplex verbindet die Katalyse an zwei Stellen, die durch einen Tunnel verbunden sind, der das erzeugte CO transportiert. Hydrophobe, CO‐affine Stellen innerhalb des Tunnels wirken eher wie eine Eimerkette als wie eine einfache Röhre.

Incomplete Wood-Ljungdahl pathway facilitates one-carbon metabolism in organohalide-respiring Dehalococcoides mccartyi. [PDF]
, 2014 The acetyl-CoA "Wood-Ljungdahl" pathway couples the folate-mediated one-carbon (C1) metabolism to either CO2 reduction or acetate oxidation via acetyl-CoA.
