Self-assembly and biological activities of ionic liquid crystals derived from aromatic amino acids
Does the mesomorphic behaviour of L-amino acid-based ILCs correlate with biological activity?

Structural analyses of isolated cyclic tetrapeptides with varying amino acid residues
Structural analyses of isolated cyclic tetrapeptides with varying amino acid residues were performed by applying combined IR/UV spectroscopy in the molecular beam and DFT calculations. The intrinsic structural properties especially with regard to the influence of different amino acid residues are fundamental for optimizing their binding ability.

Switching from adduct formation to electron transfer in a light–oxygen–voltage domain containing the reactive cysteine
Electron transfer can be observed instead of the naturally occurring adduct formation in the LOV1 F41Y mutant from C. reinhardtii although the reactive cysteine is present.
