2020-10-27

In modern science and technology, many optimization problems need to be solved in real time, while these classical methods cannot render real-time solutions to these optimization problems, especially large-scale problems. As a new metaheuristic, particle swarm optimization (PSO) [18], [19] has prove

Recent studies have shown that the extracellular regulated protein kinase 1 and 2 (ERK1 and ERK2), commonly referred to collectively as ERK 1/2, are members of the mitogen-activated protein kinase (MAPK) family. This family of kinases transport signals from the surface of the cell to the nucleus, th

PGE2 exerts its functions by binding to different receptors. Four different subtypes of PGE2 receptors are found in mammals and are designated as EP1-4. These are G-protein coupled receptors that belong to a family of seven rhodopsin-like transmembrane spanning receptors. They are structurally diffe

Kinetic isotope effects (KIEs) inform on bond vibrational changes between the ground state (GS) and TS of a chemical reaction and remain one of the most powerful experimental techniques for interrogating TS structure. KIEs on enzyme reactions measured by the internal mm concentration of labeled sub

EBI2 and its ligand(s) EBI2 was found in a screen of upregulated genes in human B cells upon infection with EBV [1]. EBI2 is a G-protein (Gαi type) coupled receptor [2] but as long as 18 years after its discovery the nature of its ligand remained undisclosed. With the help of transfected cell lines

Compounds were synthesized using a facile 8-step convergent synthesis ( and ). Briefly, (Boc)cyclen (compound ) was coupled using TBTU to Fmoc- or Cbz-protected amino alkyl acids (–), followed by deprotection using 20% piperidine in DMF, or H on Pd/C, respectively (–) ().

Introduction Protein modification by ubiquitin and ubiquitin-like proteins is one of the most common and important regulatory mechanisms in biology (Finley et al., 2004, Pickart, 2004). Ubiquitination is carried out by an enzymatic cascade consisting of three steps. In the first step, ubiquitin

Since the initial identification of DNA ligase inhibitors by a structure-based approach [[18], [26]], there have been several reports describing LigI inhibitors using computer modelling and derivatives of the original DNA ligase inhibitors [[49], [50], [51]]. While these studies have shown that the

Four active site residues of Δ1-KSTD1 are fully conserved in Δ1-KSTDs from different species (Supplementary Figure S2). These residues are Tyr-119, Tyr-487, and Gly-491 from the FAD-binding domain and Tyr-318 from the catalytic domain. The structure of the Δ1-KSTD1•ADD complex revealed that the hy

Discussion The differences in the kinetic properties of L-AmDH and LeuDH presented herein reflect a different kinetic mechanism. When compared to its parent enzyme, L-AmDH displayed a different substrate binding order, lower affinity for the keto substrate, and stronger product inhibition. The tw

Moreover, the imbalance between pro and anti-inflammatory cytokine production is present in various types of diseases. The use of substances able to induce anti-inflammatory cytokines could represent an important advance in the therapeutic treatment of a range of diseases. In this context, medicinal

Experiments on the rat model of E. coli pyelonephritis, performed to investigate the relationship between the acute inflammatory processes and the permanent kidney damage (Brooks et al., 1974), have demonstrated a positive correlation between the degree of free radical-mediated renal injury and the
