  2021-01-05

  

  Enolases are among the most abundantly expressed cytosolic proteins. They are metalloenzymes that catalyze the conversion of 2-phosphoglycerate to phosphoenolpyruvate [18]. Eubacteria and archaebacteria have a single enolase gene (reviewed in [19]). Despite the lack of signal peptides or cognate pro

  2021-01-05

  

  While we previously demonstrated that TraG is inhibited by specific transglycosylase inhibitors and that enzymatic activity is strongly reduced upon mutation of the potential catalytic core (Arends et al., 2013), the enzymatic mechanism of both domains was not assigned. Here, by mass spectrometry an

  2021-01-05

  

  In mammals, neutrophil elastase is a trypsin-like serine protease stored in the azurophilic granules of naïve neutrophils [15], [16]. The catalytic activity of neutrophil elastase relies on a His57–Asp102–Ser195 triad (chymotrypsin numbering system) that functions by transfer of electrons from the c

  2021-01-05

  

  Although enantioselective accumulation of metalaxyl in organisms is an integrated outcome of bio-process including absorption, transportation, and transformation, it is observed in our study that catalysis of CYP450 may lead to the enantioselective accumulation of metalaxyl. However, the mechanisms

  2021-01-05

  

  A decrease in heme levels enables the phosphorylation of eIF2α by HRI and thereby inhibition of eIF2α activity. Indeed, the relatively small change in cytosolic heme levels in SZ PAI-039 showed downstream functional consequences manifested by almost 50% elevation in the phosphorylation of eIF2α in S

  2021-01-05

  

  Crystallographic and NMR-based analyses have revealed that RINGs and U-boxes have a common mode of interaction with E2s (Fig. 2A). The key structural elements are two loop-like regions, which, in the case of RINGs, coordinate Zn. The loops surround a shallow groove formed by the central α-helix. Tog

  The mammalian two-hybrid results described above were all obtained in 293T cells, and thus the higher RLU observed specific to the hCrm1 fusion could be consistent with human Medetomidine HCl having an unknown activator that interacts with hCrm1 HEAT repeat 9A and somehow facilitates Crm1-Rev/RRE fu

  The results showed that ethanol and acetaldehyde production was not affected by the presence of CPA-7. We observed that the concentration of ethanol increased throughout the assay up to 95–179 μL L-1 regardless of the treatment. The acetaldehyde concentration reached its highest values after 6–9 day

  Since the 1,2-dideoxy analogues, and , served as substrates for TgTCEA and TgTCEB, respectively, with the higher affinity (lower ) and lower turnover number (lower ) than their authentic substrates, PosA and PosB (such trend was more evident on analogue for TgTCEB than on analog for TgTCEA), an intr

  Introduction In addition to the canonical double stranded structure, DNA can form various higher order structures such as bulges, and various kinds of mismatches, triplexes, to the G-quadruplex (G4). Over the past decades, accumulating evidence has begun to emerge that these non-canonical structu

  2021-01-04

  

  Predictions of enzyme topology for DGAT2 are more difficult since the DGAT2 polypeptide sequences are more diverse across species than those of DGAT1. The length and function of the hydrophilic N-terminus preceding the first hydrophobic segment varies with species – for example, segments in fungi ar

  Since Slaughter’s proposal of a genetic field defect concept for the explanation of the local relapse occurrence, much evidence has accumulated for its confirmation. The last ten years brought evidence that the genetic changes in the field are frequently accompanied by epigenetic aberrations. The ep

  Recently, a sandwich-cultured hepatocyte model has been proved to be a valuable in vitro system that maintains specific hepatic cytomorphology and function relevant to drug metabolism, disposition and toxicity, and thus, closely resembles the in vivo setting. This hepatocyte model was recognized as

  Concerning firmness, postharvest calcium dips for whole fruit have been demonstrated to preserve firmness, cell wall structure (Glenn and Poovaiah, 1990), nutritional quality (Goldberg, 1984) and fruit flavour (Ortiz et al., 2009). Similarly, combinations of calcium treatment (0.5–4%) with packaging

  Then the mechanisms responsible for BPA induced up regulation of ERRγ were further investigated. Recent studies indicated that Akt and MPAK can modulate the protein levels and transcriptional activities of ERRγ (Heckler et al., 2014, Sun et al., 2014). Previous studies also indicated that BPA can ac
