2021-03-04

A major open question in the field of lipid mediators is the molecular nature of the PLA2 enzyme involved in the release of DHA and related omega-3 fatty acids from phospholipids as a first committed step for the generation of SPMs. Although by analogy with AA it is often assumed that cPLA2α may ser

2021-03-04

While we previously demonstrated that TraG is inhibited by specific transglycosylase inhibitors and that enzymatic activity is strongly reduced upon mutation of the potential catalytic core (Arends et al., 2013), the enzymatic mechanism of both domains was not assigned. Here, by mass spectrometry an

2021-03-04

According to the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB, 1992), peptidases are divided into two classes, namely exopeptidases and endopeptidases, based on their actions on substrates and their active sites, respectively. Endopeptidases inclu

A growing number of other post-translational modifications are implicated in regulation of the ubiquitin system, including substrate modification by hydroxylation, glycosylation, acetylation, methylation, modification by poly(ADP-ribose) (PAR), and attachment of ubiquitin-like modifiers. The HIF1-α

As mentioned above, there are two major pathways for the DSB repair in mammalian cells, NHEJ and HR/HDR (homology-directed repair) [13], [51]. NHEJ is active throughout the cell cycle, predominately during the G0 and G1 phases and is considered the major pathway for the DSB repair in human cells [52

2021-03-04

The inhibition of DNMT1 using 5-AZA-dC or DNMT1 siRNA increased TIMP2 protein and mRNA expression, suggesting that TIMP2 expression is down-regulated by DNA methylation in the HDFs. In addition, 5-AZA-dC treatment led to a dose-dependent decrease of DNMT1 protein expression. 5-AZA-dC is a cytosine a

2021-03-03

The enzyme cyclooxygenase (COX) or prostaglandin endoperoxide H synthase (PGHS) is the key enzyme in the conversion of arachidonic powder (AA) into prostaglandins (PGs) [1]. In 1991, researchers found that there were two isoforms of this enzyme called COX-1 and COX-2 with independent genes and diff

Stable isotope studies, applied to skeletal remains of early Pacific populations, have shown a trend toward a horticultural diet with temporal variation in response to local environmental conditions (Field et al., 2009; Kinaston and Buckley, 2013; Valentin et al., 2010, Valentin et al., 2014; Kinast

2021-03-03

The quantification and monitoring of ChEs enzymatic activities have traditionally been associated to environmental studies in order to diagnose the exposure of non-target organisms to specific anti-cholinesterasic agents (Nunes, 2011). The importance of these enzymes as biomarkers of environmental c

2021-03-03

Although we observed increases in α1-AR mediated cAMP production separately in the nucleus and cytoplasm, compartment specificity was observed for PKA activation. GPCRs and their effector proteins are commonly found in multiprotein signalosomes with A-kinase anchoring proteins (AKAPs) serving as sca

2021-03-03

Interest in the PGE2/EP4 pathway is increasing given its diverse capability of regulating central nervous system activity [13]. EP4 has a protective function by reducing cerebral injury and improving functional outcome after stroke [14], and in suppressing Venlafaxine inflammation [15]. The EP4 rec

From an industrial perspective, the low turnover numbers and limited substrate scope of α-KG halogenases still represents a significant challenge. However, in light of the fact that currently no chemical processes are available for the selective halogenation of aliphatic carbon centers in complex mo

2021-03-03

Both receptors belong to the large family of G protein-coupled receptors (GPCRs) [4,5], which often appeared as monomers, dimers and higher order aggregates [6,7]. There is evidence that these receptor-complexes can modulate the functionality and the pharmacology of the receptors [8,9] by sequesteri

2021-03-03

The β strand domain swap in the UbV.XR dimer appears to be a unique arrangement for a Ub-based dimer. In solution, free Ub has a KD of ∼5 mM for the monomer-dimer equilibrium, and the two subunits in the dimer adopt a range of relative orientations involving residues from Ub’s β sheet (Liu et al., 2
