(CH3C3H2N2)2) trinuclear units, wherein H2salox and 2-methylimidazole are deprotonated and bonded directly to Zn2+nodes through tetrahedral and pentahedral coordination by oxygen and nitrogen, respectively. Intermolecular hydrogen bonds between the hydroxyimino oxygen of H2salox and the pyrrolic ...
Although carbon is not usually considered particularly electronegative, C—H---X hydrogen bonds are also now known to be significant in proteins. DNA (Deoxyribonucleic acid) Who you are is totally dependent on hydrogen bonds! DNA, as you probably know, is the most famous of the biopolymers owi...
Hydrogen transfer biocatalysts to prepare optically pure alcohols are in need, especially when it comes to sterically demanding ketones, whereof the bioreduced products are either essential precursors of pharmaceutically relevant compounds or constitute
The common design for H2O2-responsive organic materials for enhanced cancer PDT is to immobilize organic PSs with H2O2-responsive moieties. H2O2-responsive moieties are functional groups with specific bonds such as boronic acid group [50], sulfide bond (–s–) [51], selenium bond (–Se–) [52...
C, residues making intermolecular hydrogen bonds in the protein-protein interface of the optimized geometry. D, cofactor binding site in HupK. HupK, light red ribbon; HypC, yellow ribbon; HupK residues, light red sticks; HypC residues, yellow sticks; cofactor C, cyan; N, blue, O, red ...
In the molecular function category, “hydrolase activity, acting on glycosyl bonds” and “hydrolase activity, hydrolyzing O-glycosyl compounds” were significantly enriched. Fig. 3 GO analysis of DEGs between UV-A + HRW and UV-A treatments in three main categories. BP: biological process, ...
that may take place in the junction is intermolecular proton transfer among the terminal electronegative O/N atoms in quadruple hydrogen bonds. Such an intermolecular proton transfer process results in different proton distributions between the two binding monomers, which in turn significantly changes the...
Furthermore, the relative ∇2ρc values of them are in the range of 0.02–0.15 a.u62,63,64. Hence, there are reasons to believe that two hydrogen bonds are formed in the ground-state BTS. Figure 2 The energy diagram presents energy gaps among the four stable structures (i.e., BTS...
