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

Introduction Coping with DNA damage is possible thanks to surveillance mechanisms (checkpoints), that detect the problem and promote its solution [1], [2], and to repair and tolerance pathways that remove the lesions or reduce the damage consequences [3], [4]. Failures in these processes have a h

It would be very useful if unphosphorylated CK1s could be prepared using an E. coli expression system without the troublesome in vitro phosphatase treatment. So far, it has been shown that coexpressed λPPase, a Mn2+-dependent protein phosphatase that can dephosphorylate phospho-Ser/Thr/Tyr [20,21],

Synthetic progestogens (also known as ‘synthetic gestagens’, ‘synthetic progestins’ or simply ‘progestins’) are designed to mimic the effects of progesterone (P4) and are the active pharmaceutical ingredient in many contraceptives and hormone replacement therapies. Since most progestins are derived

Grapiprant () is a selective antagonist for prostaglandin E (PGE) receptor subtype 4 (EP4) identified as a clinical candidate for the treatment of inflammatory pain associated with osteoarthritis (OA). It is currently under development for use in humans and dogs. The projected dosing regimen of grap

The key difference between the membrane zymography and classical measurements of enzyme activities in soil slurries is the enzyme-substrate accessibility. Classical enzyme assays maximize access of substrate to all potentially reactive enzyme sites by ensuring sample destruction and detachment follo

AON successfully alleviated the myotonic phenotype in DM model mice [18], [23]. To screen for an optimal AON sequence, we used 25-mer phosphorothioate 2′ O-methyl RNA molecules that covered the exon 6B or exon 7A. Unexpectedly, AON 7A (+63−8) which covers the boundary of intron 7A and exon 7A enhanc

APC/C Uses a Dynamic Cullin–RING Mechanism to Elongate Polyubiquitin Chains Human APC/C generates Lys11-linked poly-Ub chains through an entirely different mechanism, via the distinctive E2 enzyme, UBE2S 30, 31, 32. Although APC2 and APC11 are necessary and sufficient to activate UBE2S, the mecha

Two key enzymes play important roles in the bioconversion of xylitol from d-arabitol, namely d-arabitol dehydrogenase (ArDH) and NADH-dependent xylitol dehydrogenase (XDH), respectively (Qi et al., 2014). In an earlier study, we developed a high xylitol yield strain by expressing xdh in E. coli BL21

Signal transduction through IL-34/ c-FMS ligand receptor also leads to the differentiation, survival and, angiogenesis, proliferation, adhesion and migration of cells of the monocyte/macrophage lineage similar to that of CSF-1 through the various pathways-First is through FAK (Focal Adhesion Kinase)

Alternatively, procedural factors may have contributed to the conflicting results. For instance, in order to have a more circumscribed area of drug diffusion, a volume of 0.05μl was injected in experiment 1b, which is four times lower than the one used in the mentioned plus-maze investigation. Besid

DDR1 expression is upregulated in the glomeruli and tubules of injured kidneys [7], [8], [19]; however, what role this receptor plays in kidney resident NGB 2904 of is unclear. A plausible hypothesis is that DDR1 might contribute to kidney injury by directly exerting a pro-fibrotic action. In favor

Consistent with previous simulations on the DFG-Asp-out/-in interconversion of Abl kinase, we only observe the DFG flip with protonated Asp747 (Shan et al., 2009). We showed previously that the pKa for the DFG-Asp in Abl is elevated at 6.5. Further “constant pH” simulations whereby protonation event

In most cases, the ligand affinity between subtypes is similar, but their tissue distribution is different. In the case of the estrogen receptors (ER), two subtypes (ERα and ERβ) exist (Kuiper et al., 1996) and ERβ has several isoforms, designated ERβ1–5 (Moore et al., 1998) or ERβcx (Ogawa et al.,

There is a considerable molecular genetic heterogeneity within ES/PNET. As mentioned above, either or can rearrange with in these gene fusions. Furthermore, for either gene fusion, additional heterogeneity stems from the location of the genomic breakpoints of the translocation, resulting in differen
