Hydrogen mass repartitioning (HMR) that permits time steps of all-atom molecular dynamics simulation up to 4 fs by increasing the hydrogen atoms has been used in protein and phospholipid bilayers simulations improve conformational sampling. Molecular input generation via CHARMM-GUI now supports HMR for diverse programs. In addition, considering ambiguous pH at bacterial outer membrane surface, different protonation states, either −2e or −1e, phosphate groups lipopolysaccharides (LPS) are...

Curcumin, a major active component of turmeric, has previously been reported to alleviate liver damage. Here, we investigated the mechanism by which turmeric and curcumin protect against carbon tetrachloride (CCl4)-induced injury in rats. We hypothesized that extract from CCl4-induced reducing oxidative stress, inhibiting lipid peroxidation, increasing glutathione peroxidase activation.Chronic hepatic stress was induced single intraperitoneal injection CCl4 (0.1 ml/kg body weight) into...

Interferon-induced transmembrane proteins (IFITM1, 2, and 3) are important antiviral that active against many viruses, including influenza A virus (IAV), dengue (DENV), Ebola (EBOV), Zika (ZIKV), severe acute respiratory syndrome coronavirus (SARS-CoV). IFITM exhibit specificity in activity, but their distinct mechanisms of action regulation unclear. Since S-palmitoylation cholesterol homeostasis crucial for viral infections, we investigated interactions with by photoaffinity cross-linking...

Interferon-induced transmembrane proteins (IFITMs) are S-palmitoylated in vertebrates that restrict a diverse range of viruses. IFITM3 particular engages incoming virus particles, prevents their cytoplasmic entry, and accelerates lysosomal clearance by host cells. However, how S-palmitoylation modulates the structure biophysical characteristics to promote its antiviral activity remains unclear. To investigate site-specific controls activity, we employed computational, chemical, approaches...

ABSTRACT Diacylglycerol O‐acyltransferase 1 (DGAT1) is an integral membrane protein that uses acyl‐coenzyme A (acyl‐CoA) and diacylglycerol (DAG) to catalyze the formation of triacylglycerides (TAGs). The acyl transfer reaction occurs between activated carboxylate group fatty acid free hydroxyl on glycerol backbone DAG. However, how two substrates enter DGAT1's catalytic chamber interact with DGAT1 remains elusive. This study aims explore structural basis substrate recognition by...

Phase change materials (PCMs) have been used in various fields including the of buildings. In this research, mixed shape-stabilized PCMs (Mixed SSPCMs) were prepared by impregnating coconut oil and n-hexadecane into exfoliated graphite nanoplatelets (xGnP) through a vacuum impregnate method. Coconut is fatty acid ester PCM which relatively economical comparison to other PCMs, paraffin that has high latent heat capacity. Drawbacks include leakage liquid state low thermal conductivity resolved...
