Structural and functional insights into lysine acetylation of cytochrome c using mimetic point mutants
(Wiley-Blackwell, 2021)
Post-translational modifications frequently modulate protein functions. Lysine acetylation in particular plays a key role in interactions between respiratory cytochrome c and its metabolic partners. To date, in vivo ...

Biomimetic polymers of plant cutin: An approach from molecular modeling
(Springer, 2014)
Biomimetics of materials is based on adopting and reproducing a model in nature with a well-defined functionality optimized through evolution. An example is barrier polymers that protect living tissues from the environment. ...

Origin and evaluation of the four-spin operators in magnetic lattices
(American Physical Society, 2004)
The four-spin operators are suspected to have a significant amplitude and an impact on the collective properties in spin ladders and magnetic two-dimensional lattices. They originate from cyclic circulation of electrons ...

Formation of a rotaxane from the end-capping process of a pseudorotaxane. Effects of the solvent
(American Chemical Society, 2008-08)
The effects that the solvent exerts on the end-capping process of a pseudorotaxane formed by the[Ru(NH3)5(4,4′-bpy)]2+complex and -cyclodextrin were studied. In this process the 4,4′-bpy ligand acts asrigid axle and the ...
