  Enzyme mimics belong to a type of rising catalysts which show the similar function with their corresponding natural enzymes [20], [21], [22], [23], [24], [25], [26], [27], although their structures are different from natural enzymes. In the area of prodrug activation, the widely-used enzyme mimics a

  2020-01-19

  

  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

  2020-01-19

  

  Introduction Protein ubiquitination is a posttranslational modification that plays a major role in almost all cellular processes in eukaryotes (Hochstrasser, 2009; Komander & Rape, 2012). It involves the covalent attachment of ubiquitin (Ub) via its C-terminal glycine carboxylate to a primary amine

  2020-01-19

  

  Molecular modelling studies were performed on the hDHFR inhibitors identified (1, 11, 13, 14, 16, 25 and 32) to explore the structural basis of the interaction between the mentioned compounds and the human enzyme. The docking studies were performed using the X-ray crystallographic structure of the h

  2020-01-19

  

  In the present study, we investigated the role played by CRF1 and CRF2 receptors located within the mouse PAG on the anxiogenic and antinociceptive effects produced by local infusion of CRF. To block CRF receptors, we used the selective CRF1 and CRF2 Dimethyl Fumarate antagonists, respectively, NBI

  2020-01-19

  

  EP1–4 receptors belong to the family of G protein-coupled receptor (GPCR). Trafficking events such as externalization, internalization, recycling and degradation dynamically regulate GPCR cell surface density. A fast-rate of internalization and degradation reduces GPCR surface density to desensitize

  2020-01-19

  

  Why are Tfh cell dynamics so fundamentally different in naive and immune animals? Initially, GC Dasatinib Monohydrate must pass stringent affinity and specificity checkpoints to ensure only high-affinity non-self-reactive cells are selected. Therefore, restricting primary Tfh cells with the greatest

  Significantly less is known about regulation of phytocystatin gene expression. A genomic clone corresponding to the barley cystatin Icy gene has been characterized (Gaddour et al., 2001) and the function of its promoter region has been analysed by Martínez et al. (2005b). Bioinformatic analysis of t

  In summary, we show that PE significantly ameliorate HCD-induced atherosclerosis in apoE−/− mice. Dietary fiber may influence the intestinal microbiota and thus the circulating levels of SCFAs. SCFAs, such as butyrate, inhibit cholesterol uptake and promote cholesterol excretion from enterocytes. Ou

  torsion is a urological emergency that may occur at any age. To establish blood flow surgical detorsion is required in most cases while detorsion can sometimes be achieved by hand assistance. Regardless of the correction method 2 phases (I/R) negatively affect germ cells. The torsion phase decreas

  Conventional assays rely on a comparable transformation of the target analytes and the structurally similar (but not identical) proxy substrates and are commonly used to measure individual enzyme activities in (pre-treated) intact sludge flocs (Burgess and Pletschke, 2008a, Gessesse et al., 2003, Yu

  Our previous work has demonstrated that two glutamate residues (Glu-305 and Glu-331 in murine and human TPP II) in the active site are important for exopeptidase activity in mTPP II [17]. At least one of these, Glu-331, seems to form a salt bridge to the N-terminal amino group of the substrate, posi

  Introduction Nucleic acids are polyanionic and their negatively charged nucleotides allow the binding of cationic dyes, such as acridine orange (3,6-dimethylaminoacridine). Acridine orange (AO) was first synthesized in 1889, but its ability to bind nucleic acids was only reported in 1940, with grea

  Both progesterone and the calcium ionophore A23187 rely on the synthesis of cAMP by sAC to elicit exocytosis in human sperm (Fig. 2E-H and [8], [60]). We had reported earlier that digestion of endogenous cAMP with recombinant cAMP-specific phosphodiesterase 4D [9] or inhibition of its synthesis with
