DOI: 10.1002/1873-3468.13622

Abstract: Elevated fatty acid (FA) levels contribute to severe metabolic diseases. Unbalanced oversupply of saturated FAs is particularly damaging, which renders stearoyl‐CoA desaturase (SCD1) activity an important factor of resistance. A SCD1‐related oxidoreductase protects cells against… read more here.

DOI: 10.1002/cbic.202100418

Abstract: C4‐substituted fluoroprolines (4R)‐fluoroproline ((4R)‐Flp) and (4S)‐fluoroproline ((4S)‐Flp) have been used in protein engineering to enhance the thermodynamic stability of peptides and proteins. The electron‐withdrawing effect of fluorine can bias the pucker of the pyrrolidine ring,… read more here.

DOI: 10.1002/pro.5069

Abstract: Photoconvertible fluorescent proteins (pcFPs) undergo a slow photochemical transformation when irradiated with blue light. Since their emission is shifted from green to red, pcFPs serve as convenient fusion tags in several cutting‐edge biological imaging technologies.… read more here.

DOI: 10.1016/j.dnarep.2020.102913

Abstract: Radiotherapy kills malignant cells by generating double-strand breaks (DSBs). Ionizing- radiation (IR) generates "dirty" DSBs, which associates with blocking chemical adducts at DSB ends. Homologous-directed repair (HDR) efficiently removes IR-induced blocking adducts from both 3'… read more here.

DOI: 10.1016/j.electacta.2019.135003

Abstract: Abstract Hydrogen-water are the primary reactant-product pair in the fuel electrode of reversible solid oxide cells. A different dependence of polarization resistance on pH2O in fuel cell and electrolysis modes has been proven experimentally, revealing… read more here.

DOI: 10.1021/acs.biochem.8b01099

Abstract: The temperature dependence of psychrophilic and mesophilic (R)-3-hydroxybutyrate dehydrogenase steady-state rates yields nonlinear and linear Eyring plots, respectively. Solvent viscosity effects and multiple- and single-turnover pre-steady-state kinetics demonstrate that while product release is rate-limiting at… read more here.

DOI: 10.1021/acsami.2c06186

Abstract: In order to enhance the catalytic activity and improve the stability of Mn-Al oxides in acetone oxidation, it is interesting to have found that modulating and accelerating the rate-limiting step by Al substitution rather than… read more here.

DOI: 10.1021/jacs.2c07807

Abstract: Experimental 13C kinetic isotope effects (KIEs) provide unprecedented mechanistic insight into three intermolecular anti-Markovnikov alkene hydrofunctionalization reactions─hydroesterification, hydroamination, and hydroetherification─enabled by organophotoredox catalysis. All three reactions are found to proceed via initial oxidation of the… read more here.

DOI: 10.1038/s41467-024-54242-w

Abstract: A critical cell cycle checkpoint for most bacteria is the onset of constriction when the septal peptidoglycan synthesis starts. According to the current understanding, the arrival of FtsN to midcell triggers this checkpoint in Escherichia… read more here.

DOI: 10.1073/pnas.2119580119

Abstract: Significance The rate-limiting step of hexameric replicative helicases is ill-understood and this study on the eukaryotic replicative helicase CMG identifies that the catalytic ATP hydrolysis step is not the rate-limiting step, implying that a conformational… read more here.

DOI: 10.1093/jxb/ery010

Abstract: Autophagy-related proteins Atg5 and Atg7 are rate-limiting components of autophagic flux in Arabidopsis. Overexpression of ATG5 or ATG7 genes stimulates Atg8 lipidation, autophagosome formation, and autophagic flux, leading to improved plant fitness. read more here.
