Formation and structure of the ferryl [Fe=O] in-termediate in the non-haem iron halogenase SyrB2: classical and QM/MM modelling agree [PDF]
, 2017 To rationalise mechanistically the intriguing regio- and chemoselectivity patterns for different substrates of the non-haem iron/2-oxoglutarate dependent halogenase SyrB2, it is crucial to elucidate the structure of the pivotal [FeIV[double bond, length ...

Classical pathway complement activation on human endothelial cells [PDF]
Molecular Immunology, 2007 Endothelial cells regulate vascular integrity and express complement binding proteins including gC1qR/p33 (gC1qR), which recognize C1q, a subunit of the first component of the classical complement pathway. Experiments were performed to investigate classical complement pathway activation on resting endothelial cells and endothelial cells exposed to ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

A New Tool for Complement Research: In vitro Reconstituted Human Classical Complement Pathway
Frontiers in Immunology, 2018 The complement, as part of the innate immune system, represents the first line of defense against Gram-negative bacteria invading the bloodstream. The complement system is a zymogen cascade that ultimately assemble into the so-called membrane attack ...

New trends for metal complexes with anticancer activity [PDF]
, 2008 Medicinal inorganic chemistry can exploit the unique properties of metal ions for the design of new drugs. This has, for instance, led to the clinical application of chemotherapeutic agents for cancer treatment, such as cisplatin. The use of cisplatin is,

Novel Evasion Mechanisms of the Classical Complement Pathway [PDF]
The Journal of Immunology, 2016 Abstract Complement is a network of soluble and cell surface-associated proteins that gives rise to a self-amplifying, yet tightly regulated system with fundamental roles in immune surveillance and clearance. Complement becomes activated on the surface of nonself cells by one of three initiating mechanisms known as the classical, lectin,

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Intertwined electron-nuclear motion in frustrated double ionization in driven heteronuclear molecules [PDF]
, 2017 We study frustrated double ionization in a strongly-driven heteronuclear molecule HeH$^{+}$ and compare with H$_2$. We compute the probability distribution of the sum of the final kinetic energies of the nuclei for strongly-driven HeH$^{+}$. We find that
