  Recently, a non-proteolytic role of COP1 in stabilizing PIF3 proteins in the dark has been revealed . Previous studies have shown that the endogenous levels of PIF3 protein in etiolated seedlings were nearly undetectable . Ling found that the GSK3-like kinase BRASSINOSTEROID-INSENSITIVE 2 (BIN2) p

  2021-08-30

  

  Structure similarity searches were conducted using the standalone version of the DALI program with the query structures scanned against a local current version of the PDB that has all chains as separate entries (Holm and Sander, 1995). The structural hits for each query were collected, even if the D

  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

  2021-08-30

  

  Oxidation of N-hydroxyguanidine 1 by DbH was studied by HPLC and some oxidation products for 1 could be characterized. The compounds generally observed with iron-containing systems are 4-methoxyphenylurea 11 and 4-methoxyphenylcyanamide 12 (Fig. 2). Oxidation of N-(4-chlorophenyl)-N′-hydroxyguanidin

  Given the structural similarity of BMAA to other amino acids, our hypothesis was that N-nitrosation of BMAA might result in a toxic alkylating agent, providing a previously unrecognised mechanism for BMAA action. Materials and methods Results and discussion We first examined whether chemical

  Acknowledgements Introduction Laryngeal cancers are the most frequent cancers of the head and neck region and their occurrence is strongly associated with the exposure to cigarette smoke and the consumption of strong alcohols. Almost all laryngeal cancers are squamous cell carcinomas. Usually

  Atypical collagen glycosylation The disaccharide Glc(α1-2)Gal(β1-O) decorating collagens is strongly conserved across the animal kingdom, yet for every rule, nature provides exceptions. The deep-sea worm Riftia pachyptila of the phylum Annelida represents an intriguing exception. R. pachyptila is

  For statistical analysis, the Statistical Package for Social Sciences (SPSS) was used (version 21.0; SPSSInc., Chicago, IL). Chi-square (x2) exact test was used for the comparison of categorical data, whereas Wilcoxon and Mann–Whitney U tests were used for the analysis of nonparametric variables bas

  Expression of EBI2 and its function for migration in vitro in T cells was recently reported (Chalmin et al., 2015, Hannedouche et al., 2011, Liu et al., 2011, Pereira et al., 2009). Pereira et al. (2009) used an EBI2 reporter mouse and found that most CD4+ T cells, but only approximately half of the

  2021-08-30

  

  From a mechanistic standpoint, the BCL6 RD2 domain represses the GPR183 and S1PR1 loci by recruiting HDAC2, but not MTA3-NuRD, to suppress the enhancer activation mark H3K27ac at their distal regulatory elements. However, these data do not exclude the possibility that other as yet unknown corepress

  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 fty generated recognized specific E1 forms (E1-114, E1-90 and E1-67 with anti-gNTE1; and E1-47 with anti-gE1CT); the patt

  Introduction Maintenance of genome integrity is essential for life, and faithful DNA replication and repair ensure this. One of the most important parameters for DNA maintenance is the regulation of optimal concentrations of the four 5′-deoxyribonucleoside-triphosphates (dNTPs) the precursors for D

  Although it is believed that CYP induction is regulated in humans in principle in the same fashion as in animals, some species differences in CYP3A enzymes induction were observed. Rifampicin is known to be a potent inducer of CYP3A4 in human hepatocytes, whereas pregnenolone-16α-carbonitrile (PCN)
