Sterically Controlled Interfacial Charge‐Transfer Mechanisms in Unsymmetrical Squaraine Dyes for Suppressed Aggregation and Enhanced Performance in High‐Efficiency Dye‐Sensitized Solar Cells

ChemistryOpen, Volume 15, Issue 5, May 2026.
Molecular engineering of cis‐configured unsymmetrical squaraine dyes reveals how branched alkyl substituents regulate aggregation and interfacial charge–transfer processes on TiO2. Steric shielding suppresses H‐type aggregation and retards interfacial recombination, leading to enhanced recombination resistance and improved open‐circuit voltage.

Substrate selectivity of human histidine methyltransferase METTL9

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Methylation of histidine residues in zinc transporters by histidine methyltransferase METTL9 plays an important role in modulating their metal‐binding properties. Here, we report synthetic, enzymatic, and computational studies on human METTL9‐catalyzed Nπ‐methylation of His375 in zinc transporter SLC39A5‐derived peptides in which the histidine

Fluctuating β‐Sheet Secondary Structure in DS119 Explains the Small Effects of Backbone N‐Amination on Thermal Stability

Journal of Peptide Science, Volume 32, Issue 5, May 2026.
Residues with backbone N‐amination have been introduced into a region of parallel β‐sheet secondary structure. Contrary to predictions, the N‐amination of Trp9 or Phe33 did not give an increase in the thermal stability of DS119. MD simulations suggest this is due to the highly fluctuating nature of the β‐sheet region. ABSTRACT The miniprotein DS119 has
