  The focus of this review is on the diacylglycerol acyltransferase (DGAT, EC 2.3.1.20) enzymes, DGAT1 and DGAT2, that catalyze the esterification of a fatty acyl moiety to a DAG molecule to produce TAG. These enzymes commit DAG to being stored as TAG rather than being diverted for the synthesis of ph

  Introduction Biocatalysis can be used to synthesize chiral building blocks, such as monomers for polymer materials, and precursors for pharmaceuticals [[1], [2], [3], [4]]. Enzymes are very suitable for catalyzing reactions with high enantioselectivity to obtain chiral products. For instance, alc

  One of the hallmarks of the terminal stages of apoptosis is the fragmentation of chromosomal DNA that proceeds in a two-step manner: the DNA is initially cleaved into 50–300kb fragments and eventually into oligonucleosomal pieces [12], [13]. The two major apoptotic nucleases are DNA fragmentation fa

  Arsenic is an endocrine disruptor with estrogenic activity. Further study has shown that arsenic exposure can significantly increase the expression of estrogen receptor-related genes, steroid metabolism-related enzymes and lung cancer-related genes in the lung tissues of female mice on the occurrenc

  In mammals, neutrophil elastase is a trypsin-like serine protease stored in the azurophilic granules of naïve neutrophils [15], [16]. The catalytic activity of neutrophil elastase relies on a His57–Asp102–Ser195 triad (chymotrypsin numbering system) that functions by transfer of electrons from the c

  It is interesting to note that SIS3 our results show a very similar behavior in binding of DDR2 ECD to immobilized a-telo (bovine-dermal) versus telo- (rat-tail) collagen I as a function of its oligomeric state. Thus, the telopeptide region of tropocollagen exerts little influence on DDR2-collagen

  Based on the similar activities of Rad6p and Cdc34p (i.e., both are E2 ub-conjugating enzymes) on ubiquitinylation of p33 replication protein, we propose that Rad6p and the plant Ubc2p mono- and bi-ubiquitinate the viral replication proteins in order to facilitate the recruitment of the cellular ESC

  The authors identified inhibitors of SUMOylation using two assays to monitor the conjugation of SUMO1 to RanGAP1 by E1 and E2 enzymes: a fluorescence resonance energy transfer (FRET) primary screen that evaluated over 250,000 compounds and a chemiluminescence secondary screen. A counter screen was u

  After incorporation of random 78 7 receptor by TdT during heavy-chain rearrangements, both TdT and pol λ may perform in trans polymerase activity (in unknown proportions), whereas synthesis of the complementary strand can only be achieved by pol λ using its gap-filling activity, which TdT lacks bec

  Acknowledgments Introduction Understanding the characteristics of the Amazonian Dark soils “Terras Pretas de Índio” (TPIs) is of ecological importance, because the TPI soils represent a residue-based model for tropical sustainable agriculture (Sombroek et al., 2003, Neves et al., 2003, Cohen-O

  2020-05-11

  

  Estrogen-related receptors (ERRs) are orphan nuclear receptors and have three members including ERRα, ERRβ, and ERRγ (Yasumoto et al., 2007). Though they are termed as ERRs due to the sequence homology with estrogen receptors, they don’t need to bind estrogens to exert action. Generally, ERRs bind t

  The mechanisms by which Cav-1 enhances embryonal tumor progression are currently unknown. Given the documented ability of Cav-1 to drive increased biogenesis of caveolae and accelerate the flow of nutrients (mostly glucose and fatty acids) across the membrane, as observed in particular in adipocytes

  As proof of principle, the effect of selective blockade was measured using TAK-044, a peptide antagonist with approximately 250-fold selectivity for the ETA subtype over ETB as measured by ligand binding in the human heart. A 30-mg infusion over 15 minutes of TAK-044 (providing a serum concentration

  Studies have shown that endothelial cells damaged by SAH can release a large amount of ET-1, thus its plasma level is elevated and is positively correlated with the symptoms of SAH (Lei et al., 2015, Masaoka et al., 1989). Our data obtained from SAH-along rabbits were consistent with these findings.

  The AURA trial was a phase I/II study evaluating the safety, tolerability and activity of Osimertinib in patients with EGFR-mutated NSCLC progressing after a previous EGFR TKI. The phase I component of the study included a dose escalation part (Osimertinib 20mg to 240mg), using a rolling six design,
