2021-08-26
Our data supports the conclusion that the exonuclease activity thought to be intrinsic to Artemis is not a component of the Artemis polypeptide. Many possibilities exist to explain the presence of the exonuclease activity in less-pure fractions of Artemis. It is possible that the exonuclease is simp

Enzymes repairing alkylated DNA Induction of the Ada regulon Methylated Ada is a strong activator for ada and alkA promoters. Although much weaker than the methylated form, unmethylated Ada acts alone as an activator for ada and alkA promoters. In contrast, the unmethylated protein present in

We examined the function of immobilised THPs by seeding cells transfected with DDR2-Flag on derivatised crosslinked collagen films, then detecting the phosphorylation of tyrosine 740 (Y740) on the intracellular domain of DDR2 [50]. This regulatory residue is a target for the intracellular tyrosine k

2021-08-26
Proteases, as multifunctional enzymes, play key roles in controlling a wide variety of cellular and extracellular processes in plants and animals, including protein degradation and processing, germination, complement activation, inflammation, responses to environmental stimuli, senescence and so on.

Atipamezole hydrochloride (Fig. S1), an α2-adrenoceptor antagonist, is commonly used by veterinarians to recover animals from sedation-anesthesia induced by α2-adrenoceptor agonists. Recent studies in animals suggest that atipamezole might have beneficial effects in IRAK-1-4 Inhibitor I damage repa

The strong adsorption of amines to the stationary phase of gas chromatography (GC) columns causes issues such as tailing, ghosting and low reproducibility [12], [13]. A common practice to overcome this problem is the chemical derivatisation of amines prior to GC analysis [14]. Comprehensive reviews

2021-08-26
In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B. An

The aim of the following work was to untap the potential of DIS as a low-cost substrate for fungal production of lignocellulolytic enzymes via SSF. Fungal strains with the ability to transform the unpretreated DIS to a mixture of industrially relevant lignocellulases were identified. Furthermore, th

In addition to vasoconstrictor actions (acute effects), ET-1 exerts potent mitogenic actions on vascular smooth muscle cells and cardiac myocytes (chronic effects), hence causing vascular and cardiac hypertrophy [19,24,25]. These effects are mediated via stimulation of either ETA or ETB receptors, a

A comparative analysis of the cleavage activity of different forms of the BoNT/A endopeptidase in reduced conditions with SNAPtide and full-length SNAP-25 substrate is summarized in Fig. 5, Fig. 6. The BoNT/A LC was found to be the most active against SNAPtide, a small peptide segment of the SNAP-25

We first confirmed LPS-induction of markers known to induce NF-κB signaling in Caco2BB cells, as established for numerous other cell types [31]. We initially selected this approach to monitor NF-κB activation instead of directly monitoring p65 as it is technically straightforward and provides both u

A major finding to emerge from this study is a conserved regulatory scheme deployed by both innate and adaptive lymphocytes, which is coordinated by a cohort of TFs. The scheme functionally compartmentalizes effector cGMP Dependent Kinase Inhibitor Peptide that circulate between blood and peripher

We propose the following model for how B cell-guiding EBI2 ligand gradients are established in lymphoid tissues. CH25H and CYP7B1 are needed in radiation-resistant stromal cells, are abundantly expressed and active in CXCL13+ and CCL21+ FRCs, but not lymphocytes, and are poorly expressed in the inne
