  In this report, we evaluate if this molecular mechanism is used universally by high-fidelity DNA polymerases during the replication of DNA lesions that are structurally distinct from abasic sites. This was approached by quantifying the kinetic parameters for the incorporation of modified and non-nat

  Here we uncover a highly diverse superfamily of self-replicating MGEs, dubbed pipolins, which are present in three major bacterial phyla, as well as in mitochondria, and encode divergent PolB carrying TPR1 and TPR2 subdomains. Biochemical characterization of a representative enzyme encoded by a pipo

  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

  Imatinib (STI-571) is a first-line tyrosine kinase inhibitor (TKI) targeted at breakpoint cluster region-Abelson kinase (ABL) for the treatment of chronic myeloid leukemia (CML) [26]. As a type II inhibitor, imatinib achieves significant selectivity by binding to an inactive DFG-out conformation (DF

  To investigate the role of DPP-4 inhibition in inflammation-induced bone resorption, we evaluated the effect of a DPP-4 inhibitor on LPS-induced osteoclast formation and bone-resorption in vivo. Our results showed that the DPP-4 inhibitor inhibited LPS-induced osteoclast formation and bone resorptio

  Till date, several predictive models have been developed by different research groups to speed up the process of library selection and drug optimization (Walters et al., 1999, Caldwell, 2000, Plewczynski et al., 2006, Wang and Ramnarayan, 1999, Pogorelcnik et al., 2015, Greenbaum et al., 2002, Sadow

  Experimental procedures Introduction Perfluorooctane sulfonate (PFOS) is an anthropogenic compound with high thermal, chemical and biological stability, which makes it a perfect ingredient for many industrial applications (Kissa, 2001). Nevertheless, these characteristics also mean that PFOS i

  Several effective strategies have been developed to design activatable MR probes according to the Solomon, Bloembergen and Morgan (SBM) theory, including modulation of the number of inner-sphere water molecules (q), the rotational tumbling time (τ) and the residence lifetime of inner-sphere water mo

  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.

  As expected, the 19-nortestosterone-derived progestins tested were moderate agonists of hAR (C), with EC50s ranging from 2 to 10nM, however all were less potent than the endogenous ligand DHT by at least a factor of 6, with relative potencies ranging from 0.0301 to 0.164. This is in agreement with p

  In the present work, we ask whether rNMP incorporation is an evolutionarily conserved property of DNA synthesis in Archaea. For this purpose, we used the best characterized hyperthermophilic anaerobe, Pyrococcus abyssi GE5 [47]. This strain duplicates its genome as fast as Bacteria, supported by euk
