Unexpected steric hindrance failure in the gas phase F− + (CH3)3CI SN2 reaction
Nature Communications, 2022 Base-induced elimination (E2) and bimolecular nucleophilic substitution (SN2) are of significant importance in physical organic chemistry. Here, the authors show that the competing factor of E2 as opposed to steric hindrance determines the low reactivity

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

BiomoleculesThe pH dependence of the free energy level of the flash-induced primary charge pair P+IA− was determined by a combination of the results from the indirect charge recombination of P+QA− and from the delayed fluorescence of the excited dimer (P*) in the ...

SnapShot: The Germinal Center Reaction
Cell, 2014 To produce high-affinity antibodies, B cells must undergo iterative cycles of targeted mutagenesis and affinity-based selection. These cycles take place in a structure known as the germinal center, which forms in secondary lymphoid organs upon exposure to antigenic stimuli. Here, we summarize our current understanding of the germinal center reaction.

The Binding Pockets of QA and QB in the Photosynthetic Reaction Center of Rba. sphaeroides Probed by Pulsed EPR [PDF]
, 2011 The bacteria Rhodobacter sphaeroides uses photosynthetic reaction centers to convert light into chemical energy. Light absorption by the reaction center results in electron transfer through a series of cofactors, the final two are identical ubiquinones

Phenomenal Diversity of the Photosynthetic Apparatus Evolved in Aerobic Anoxygenic Phototrophs
MicroorganismsAerobic anoxygenic phototrophs (AAPs) are intrinsically paradoxical; these species use a pathway commonly found in oxygen-deprived environments called anoxygenic photosynthesis, as a supplementary energy source to their obligately aerobic respiration. At

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
