  2021-06-01

  

  DNA-PK (Jackson, 1997) is activated by DNA double-stranded breaks (DSBs). It is a trimeric complex composed of the catalytic subunit, DNA-PKcs, and the Ku70/80 heterodimer. DNA-PK mediates non-homologous end joining (NHEJ), which joins programmed DSBs created during V(D)J recombination and class swi

  2021-06-01

  

  In laboratory strains of Escherichia coli, three mechanisms of repair for alkylated bases are known. The first involves constitutively expressed Ogt and inducible Ada methyltransferases, directly removing methyl groups from O6-methylguanine (O6meG) and O4-methylthymine (O4meT) [1], [2], [3], [4]. In

  2021-06-01

  

  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

  2021-06-01

  

  Given the importance of cysteine cathepsin inhibitors as putative therapeutic molecules and microbial virulence factors, we chose to investigate whether Yersinia enterocolitica may be a potent producer of such inhibitors. Y. enterocolitica is the most heterogeneous species within the genus Yersinia.

  Conclusion CSF-1R may contribute to limitation of targeted therapies by providing EGFR-bypassing signals that support proliferation. Multi-kinase inhibitors such as cabozantinib are available, and agents targeting CSF-1R are in clinical trials, however, at present, as inhibitors of tumor-associat

  The P4H activity and the large number of 4-Hyp residues that are formed, amounting to half of all the Pro residues or 10% of all residues, have been identified as having a clear role in the structure and chemistry of the triple helix [3]. The role of the rare 3-Hyp residues is less clear and is sti

  2021-06-01

  

  In the course of carbohydrate metabolism, pyruvate, the end product of glycolysis, is converted to acetyl-CoA, which fuels the citrate cycle for further generation of energy. In the case of elevated levels of acetyl-CoA, acetyl-CoA is converted into malonyl-CoA by the action of acetyl-CoA carboxylas

  Menopausal hormone therapy, from the beginning to WHI Estrogen products have been used since the 1940s, with increasing prescription through the 1960s. First concerns appeared in the 1970s when oral treatment was linked to uterine cancer. Oral estrogens have traditionally been coupled with proges

  EC barrier dysfunction triggered by inflammatory mediators involves more than one mechanism, explaining the partial attenuation of EC barrier compromise obtained with PKA and Epac activators. PKA-dependent phosphorylation of vasodilator-stimulated phosphoprotein (VASP) has been shown to make a posit

  Introduction Enzymes have higher selectivity, specificity and efficiency than chemical catalysts. Due to their properties and their green chemistry, biocatalysts are widely used in food, textile and pharmaceutical industry [1], [2]. A high efficient biocatalyst for industrial applications must be s

  Analytical improvements Since our review of “Oxysterol Metabolomes” in 2011 [7], there have been a number of improvements in analytical methods for the analysis of oxysterols and related compounds.

  Currently, much effort has been made to design and synthesize ThDP analogs (such as ThTDP, ThTTDP, and triazole-ThDP in Fig. 2)8, 9, 10, 11, 12 as PDHc E1 inhibitors. These ThDP analog inhibitors, such as ThTDP and ThTTDP, can block the ThDP binding site, and exhibit significantly stronger binding a

  Immunofluorescence assays were performed to localize the enzyme during growth and differentiation to further characterize Giardia E1. As stated before, the assays showed that the IAA-94 generated recognized specific E1 forms (E1-114, E1-90 and E1-67 with anti-gNTE1; and E1-47 with anti-gE1CT); the p
