The Fe–V Cofactor of Vanadium Nitrogenase Contains an Interstitial Carbon Atom

open access: yesAngewandte Chemie, 2015
The first direct evidence is provided for the presence of an interstitial carbide in the Fe–V cofactor of Azotobacter vinelandii vanadium nitrogenase. As for our identification of the central carbide in the Fe–Mo cofactor, we employed Fe Kβ valence-to ...

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Overcoming barriers for investigating nickel-pincer nucleotide cofactor-related enzymes

open access: yesmBio
The nickel-pincer nucleotide (NPN) cofactor is a modified pyridinium mononucleotide that tri-coordinates nickel and is crucial for the activity of certain racemases and epimerases. LarB, LarC, and LarE are responsible for NPN synthesis, with the cofactor

A role for cofactor-cofactor and cofactor-histone interactions in targeting p300, SWI/SNF and Mediator for transcription

open access: yesThe EMBO Journal, 2003
Transcriptional activation from chromatin by nuclear receptors (NRs) requires multiple cofactors including CBP/p300, SWI/SNF and Mediator. How NRs recruit these multiple cofactors is not clear. Here we show that activation by androgen receptor and thyroid hormone receptor is associated with the promoter targeting of SRC family members, p300, SWI/SNF ...

Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

open access: yesAdvanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Altered cofactor regulation with disease-associated p97/VCP mutations

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2015
Significance Age-associated degenerative diseases have similar pathogenic mechanisms related to defects in protein homeostasis. p97/VCP (valosin-containing protein) is essential for coordinating protein degradation and is mutated in a multisystem ...

Bioinspired Design of Heterogenous Single‐Atomic‐Site Catalysts for Electrocatalysis and Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review gives a summary on the representative bioinspired single‐atomic‐site catalysts (SACs) and their applications in heterogeneous electrocatalysis and photocatalysis. The fundamentals of bioinspired design strategies are systematically discussed in the context of the first shell coordination, the second/long‐range coordination, and the outer ...

Sulfite: Cytochrome \u3cem\u3ec\u3c/em\u3e Oxidoreductase from \u3cem\u3eThiobacillus novellus\u3c/em\u3e [PDF]

open access: yes, 2000
Direct oxidation of sulfite to sulfate occurs in various photo- and chemotrophic sulfur oxidizing microorganisms as the final step in the oxidation of reduced sulfur compounds and is catalyzed by sulfite:cytochrome c oxidoreductase (EC1.8.2.1).

Reduction of Order, Periodicity and Boundedness in Nonlinear, Higher Order Difference Equations

open access: yes, 2012
We consider the semiconjugate factorization and reduction of order for non-autonomous, nonlinear, higher order difference equations containing linear arguments. These equations have appeared in several mathematical models in biology and economics.
