Abstract Exocytosis depends on cytosolic domains of SNARE proteins but the function transmembrane (TMDs) in membrane fusion remains controversial. The TMD protein synaptobrevin2/VAMP2 contains two highly conserved small amino acids, G 100 and C 103 , its central portion. Substituting and/or with β-branched acid valine impairs structural flexibility terms α-helix/β-sheet transitions model membranes (measured by infrared reflection-absorption or evanescent wave spectroscopy) during increase...
A graphene-spin crossover (SCO) complex hybrid (Gr-SCO-A), prepared by non-covalently anchoring a pyrene tethered iron(<sc>ii</sc>)-SCO <bold>1</bold> with single/few layer graphene sheets, shows persistent thermal and light induced SCO.
Abstract New π‐conjugated structures are constantly the subject of research in dyes and pigments industry electronic organic field. In this context, triphenodioxazine (TPDO) core has often been used as efficient photostable once integrated air stable n‐type field‐effect transistor (OFET). However, little attention paid to TPDO soluble materials for optoelectronic devices, possibly due harsh synthetic conditions insolubility many compounds. To benefit from photostability dye‐sensitized solar...
A new class of redox-active ligands merging catechol and alloxazine structures is reported. trimetallic triangular complex formed upon complexation to nickel.
The far infrared (FIR) and Raman fingerprints of the halogen bond in two representative 1D bonded networks based on recognition TFIB, tetrafluorodiiodobenzene, with piperazine or azopyridine, have been accurately identified. It was demonstrated that signature bonding solid state, especially N⋯I signal can be simply directly evidenced region. DFT theoretical calculations identified interaction molecular crystals allowed estimation corresponding energies distances involved bonds, accordance...
Biological membranes are potentially involved in the transport of metal ions, such as Ti(IV), and, sometimes, their associated ligands. Understanding interactions Ti(IV) ions and complexes with biological provides a basis for elucidating action mechanism titanium anticancer drugs. Herein, we investigated two neutral titanium(IV) complexes, viz. [H2Ti(Cat)3] (1) [H2Ti(Napht)3] (2), incorporated into DOPC multi-bilayers using ATR-FTIR spectroscopy. Infrared results showed that 1 2, when...
Hemocyanins are large oligomeric respiratory proteins found in many arthropods and molluscs. Here we give infrared spectroscopic evidence of a high stability towards exposure to sub-zero temperatures for hemocyanins from the Limulus polyphemus Eurypelma californicum at different pH values. Small but distinct temperature induced changes secondary structure were observed, stable core least 40% α-helical is preserved as identified spectra obtained between 294 20 K. The structural differ detail...
Surface enhanced infrared absorption spectroscopic studies (SEIRAS) as a technique to study biological molecules in extremely low concentrations is greatly evolving. In order use the for identification of structure and interactions such molecules, it necessary identify effects plasmonic electric-field enhancement on spectral signature. this properties 1,2-Dipalmitoyl-sn-glycero-3 phosphothioethanol (DPPTE) phospholipid immobilized gold nanoantennas, specifically designed enhance vibrational...
