  2020-05-16

  

  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

  Experimental Procedures DNA synthesis reagents were purchased from Glen Research (Sterling, VA). A solution of 0.1 M triethylamine acetate (TEAA) (pH 6.5) was used as HPLC buffer A, and HPLC-grade acetonitrile from Oceanpak (Sweden) was used as HPLC buffer B. All other chemicals were obtained fro

  2020-05-16

  

  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.

  2020-05-16

  

  Two major mechanisms including apoptosis and oxidative stress have been suggested for MTX-induced cytotoxicity (Hafez et al., 2015; Neuman et al., 1999; El-Sheikh et al., 2015). It has been reported that MTX promotes cell death via apoptosis in both cancerous and non-transformed cells (Mazur et al.,

  Orange-spotted grouper (Epinephelus coioides) is a coral reef fish with a high commercial value in China and Southeast Asian countries. However, in recent years, various outbreaks of viral diseases have affected the grouper aquaculture industry (Wei et al., 2010). Specifically, Singapore grouper iri

  Ligand binding (RTK activation) induces the endocytic internalization of RTKs, and this has been demonstrated for CSF-1R [15], [16], [17]. Endocytosed RTKs are targeted to the lysosome, which we and others have established to be dependent on ubiquitination via CBL-family and recognition by ESCRT com

  A neurotoxic syndrome called “Intermediate syndrome” has been described after acute cholinergic crisis, which has been interpreted as the result of pre- and postsynaptic disruptions of neuromuscular transmission (Senanayake and Karalliedde, 1987). Other toxic effects with unknown molecular targets

  One possibility to differentiate between the two failure modes, and also to identify the corresponding characteristics of the resulting fracture surface, is a series of FNCT measurements with varying nominal (initial) stress. The dependence of the observed time to failure tf on the actual stress cha

  The mRNA expression of asEP4 studied by RT-PCR shows that EP4 is expressed in many different tissues in Atlantic salmon which is comparable to other species (Sugimoto and Narumiya, 2007) although some distinct differences are present. For example, in mice the expression of EP4 receptor was found to

  Using HPLC and an amino scopolamine hydrobromide sequencer, the site of cleavage into the fluorogenic substrate AbzFRQEDDnp, determined as specific to the endopeptidase STH2, was analyzed and identified as being R2-Q3, and into substrate AbzFGQEDDnp, determined as specific to SH1, it was G2-Q3 (Fig

  Phenotypic responses: alkylation-induced cell death and mutagenesis E. coli alkB mutants were isolated in a screen for strains specifically sensitive to the cytotoxicity of MMS but not UV-irradiation. This was the first indication that the AlkB protein is a primary cellular defence against alkyla

  Conclusions The PQQ-dependent CcPDH is the first PQQ-dependent enzyme identified in eukaryotes. The PQQ cofactor binds the enzyme with high affinity, reflected in a Kd of 1.1 nM, and the enzyme oxidizes 2KG, l-fucose, and rare sugars such as d-arabinose and l-galactose. The AA8 cytochrome b domai

  CXCL16 mediated cell migration is facilitated by the interaction of soluble CXCL16 with CXCR6, expressed predominantly on the cell surface of CD4+ Th1 cells, cancer infiltrating lymphocytes and platelets (Borst et al., 2012, Kim et al., 2001, Liao et al., 1997, Wilbanks et al., 2001). CXCR6 is invol

  A variety of fused 6–5-membered ring chemotypes have arisen such as 7-azaindole acetic acids, benzimidazolyl acetic acids, spiro-indolinone acetic acids, and indolizine acetic acids, however, to the best of our knowledge, fused 5,5-membered ring systems have not been reported. Prostaglandin D (PG

  These data indicate that, in the context of the N-terminal 42 amino acids of p53, threonine 18 is a substrate for phosphorylation by CK1 as mediated by prior phosphorylation of serine 15. To determine whether this is a property of full length p53, GST-p53 fusion proteins comprising the full length p
