G, SDS-PAGE analyzed for disulfide bond formation in Y221C/G392C/D393C. The Y221C/G392C/D393C mutant forms a disulfide bond that locks in the RecA1 and RecA2 domains, leaving Dbp2 in a single state. H, the unwinding activity of Dbp2 and Y221C/G392C/D393C in the absence and...
The formation of aldimine bond produces a blue shift in the peak at 320 nm and red shift at 420 nm along with an increase in intensity. Moreover, the binding of CTAT caused a high absorbance in the 420 nm peak maxima indicating better binding of PLP to K286. PLP Pyridoxal-l-...
A Z1,Z2-migration leads to two diastereomeric adducts with a p-coordinated imine that then inserts into the Ir–H bond to give the corresponding Ir amide complexes. The previous step is a simultaneous hydrogenolysis of the Ir–N and the formation of an Ir–H bond, presumably via hetero...
Hydrogen- bond between N-terminal Met of docked peptide and Y140 of RimIMtb is represented by dotted line (b) Residues involved in hydrophobic contact between RimIMtb and N-terminal Met of docked substrate peptide, defining substrate binding pocket of the enzyme (c) Surface cartoon of binding ...
4d. As expected from the d band theory, an upward shift of the d states of active Co sites with respect to the Fermi level results in a stronger Co–O bond, strengthening the oxygen-containing intermediates adsorption. However, the over upward shift of d states of active Co sites with ...
When a heteroatom with a different size or electronegativity from carbon replaces some of the carbon atoms in the graphene lattice, structural distortion or bias in the charge density distribution occurs in the graphene network, leading to the formation of active sites on the heteroatom-doped ...
The production of H2 decreased as a result of side reactions that were still occurring after 2 h of reaction time, such as the CO2 to CO/CH4 formation. The evolution of H2 decreased as a result of potential side reactions that may have been active after 2 h of reaction time due to ...
Nonetheless, ethanol tends to be oxidized incompletely, and the CC bond rupture is most likely not occurring avoiding the formation of CO2. In this way, the fast membrane carbonation, which causes an irreversible decrease in the ionic conductivity, is prevented, leading to better fuel cell ...
The difficulty in oxygen reduction was due to the particularly high energy of the O = O bond (498 kJ/mol) and slow activation of the kinetic (Li et al., 2016; Liu et al., 2022b). Show abstract Cu nanoclusters on N-doped carbon nanotubes as efficient electrocatalyst for oxygen ...
In the other reaction mode, intermolecular cyclization reactions gave A4- and trans-A2B2-meso-substituted porphyrins under mild reaction conditions with low scrambling. Keywords: C–C bond formation; Chemical Synthesis; dipyrromethane; heterocyclic chemistry; IUPAC Congress-44; metal triflates; ...
