2019-11-20
Among the members of the GH106 family, which groups 319 different sequences, a single 3D-structure has been reported, the BT0986 from Bacteroides thetaiotaomicron that shows a (β/α)8 barrel and catalyzes the hydrolysis of an α-l-rhamnopyranoside bound to the C2 position of an arabinofuranoside (L-Rh

A structural explanation for how RBR RING1s handle their bound E2~Ubs differently from canonical RINGs has not been readily apparent. Only a few residue positions are strongly conserved in RING and RING1 domains, most of which are zinc-coordinating Cys and histidine residues. A key position in canon

The absence of the LIG3 gene in yeasts has prevented the use of genetically tractable lower eukaryotes, such as Saccharomyces cerevisiae and Schizosaccharomyces pombe, as models to gain insights into the cellular functions of and interplay between the DNA ligases encoded by the LIG1, LIG3 and LIG4 g

The best preserved individuals were selected for isotope analysis of diet (Table 2). These represent 21 individuals including four subadults: two young children aged between 1.5 and 2.5 years old, one child between 7 and 11 years old and one adolescent (12–16 years old), and 17 adults including six

Introduction Tumor necrosis factor (TNF) is a pro-inflammatory mediator with the capacity to induce apoptosis (Benderska et al., 2012). Recent reports have shown that TNF might trigger cell death, at least in part, by directly affecting the reorganization of the Sodium Picosulfate cytoskeleton (Cam

Introduction Eicosanoid lipid prostaglandin D2 (PGD2) is the major prostaglandin produced by activated mast S-Adenosylhomocysteine (Lewis and Austen, 1981). The physiological function of PGD2 is mainly mediated by two G protein-coupled receptors (GPCRs), PGD2 receptor 1 and 2 (DP1 and DP2), which

A recent analysis of 2721 urine samples collected from 245 men and 408 women across the US general population between 2005 and 2010 showed that MP, PP and BuP were measurable in 99.9%, 98.3% and 73.6% of samples from women and 99.3%, 90.2% and 35.9% of samples from men, respectively (Smith et al., 2

An important role for the precursor molecule of the main EBI2 ligand, 25-OHC, in the inhibition of inflammation was recently shown. 25-OHC was demonstrated to inhibit inflammasome induction in mouse macrophages [28]. Inflammasome assemblies are the sites of caspase 1 activation and lead to the gener

2019-11-19
Introduction The ubiquitination status of a target protein is achieved via a delicate balance between two opposing forces: ubiquitin E3 ligases and DUBs. It has been postulated that the majority of proteins in a cell are regulated and modified by ubiquitin at some point (Hershko and Ciechanover,

Some family I DNA ligases can use dATP as nucleotide cofactor. For instance, human Voreloxin Hydrochloride I uses dATP with a catalytic efficiency that is only 36-fold lower in comparison to ATP [9]. EhDNAlig is unable to use dATP as a nucleotide cofactor, indicating a more constrained active site i

The interface between the E3 ligase and the E2 enzyme can vary, and ZNF451 and SP-RING ligases stabilize this interaction via noncovalent binding to a scaffold SUMO (SUMOB) on the backside of the E2 (Cappadocia et al., 2015; Eisenhardt et al., 2015; Streich & Lima, 2016). By contrast, RanBP2 does no
