  Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

  Materials and methods Results Discussion The nitric oxide generating enzymes of the NOS family comprise three isoforms: nNOS, iNOS and eNOS [31]. Expression of eNOS is mainly found in endothelial 59 7 mass where it physically promotes vasodilation [32]. Conversely, evidence also indicates

  2019-08-27

  

  All DGKs have at least two cysteine-rich regions homologous to the C1A and C1B motifs of PKCs [26]. In theory, these domains may bind DAG, perhaps localizing DGKs to where DAG accumulates. However, no DGK C1 domain has so far been conclusively shown to bind DAG. In fact, structural predictions sugge

  Mild cognitive impairment (MCI) is a clinical transitional stage between normal aging and Alzheimer disease (AD) [1]. Approximate 15–30% MCI patients convert to AD annually. Although many efforts have been taken to prevent the conversion from MCI to AD [2], [3], there are few biomarkers to predict t

  2019-08-27

  

  As mentioned previously, dopamine plays a crucial role in reducing prefrontal cortical suppression to the amygdala (Rosenkranz and Grace, 2001) and prefrontal cortex mediated amygdala supression has recently been associated with vagal regulation of HRV (Sakaki et al., 2016). In addition, evidence ha

  2019-08-27

  

  In S. cerevisiae, Mek1, a paralog of the checkpoint kinase Chk2, mediates cell-cycle arrest in response to meiotic defects (Bailis and Roeder, 2000, Xu et al., 1997). Mek1 is associated with meiotic chromosome axes, where its activation requires interactions with two other axis proteins, Hop1 and Re

  In the literature, we can find two different modes of action for estrogens: Firstly there is the commonly accepted genomic pathway. Estrogens pass the cell membrane due to their lipophilic character via diffusion and bind to estrogen receptors (ERs) in the cytoplasm. After binding a dimerization of

  Conclusions Introduction The terms endocrine active and endocrine disruptive have been used to describe an ever-expanding list of naturally-occurring and synthetic compounds that interact with mammalian hormonal systems, and in particular, the reproductive system. These compounds have been ass

  2019-08-27

  

  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

  2019-08-26

  

  Prenylation may turn a flavonoid from an agonist to an antagonist and improve the selectivity to both ERs depending on the position of the substitution. C-8 prenylation appears to promote antagonism to a larger extent than C-6 in ERα due to steric hindrance against generation of agonistic conformati

  2019-08-26

  

  The cpm corresponding to bound substrate in the sample well can be expressed as the difference between the total cpm in the sample well (3Hswtotal; 14Cswtotal) and the cpm for the unbound substrate in the sample well, as illustrated by Eq. (2): By combining Eqs. (1), (2), cpm for the bound substrat

  2019-08-26

  

  E3 ubiquitin ligases are key players in the ubiquitin-proteasome pathway because they catalyse ubiquitination of substrate proteins.39, 40, 41 As important regulators of cellular ubiquitination, E3 ligases are emerging as attractive drug targets, particularly in cancer.42, 43, 44 However, E3 ligases

  2019-08-26

  

  The occurrence of three Ag-NORs per metaphase and/or a maximum of three nucleoli per nucleus in most of the varieties may be explained by chromosomal rearrangements or unequal crossing-over events that induce the deletion of the fourth active rDNA loci. Also, the chromosome pair that showed less int

  2019-08-26

  

  The outcome of DGK function will thus depend on the binding partners of each DGK isoform, and the effects that they exert can be quite different. A clear example of this concept has been demonstrated for the type IV DGKs, ζ and ι, which are structurally very similar but have opposing effects on Ras

• DGAT is specifically responsible for endogenous synthesis

  2019-08-26

  

  DGAT2 is specifically responsible for endogenous synthesis of TAGs which are then packed into cytosolic LDs in the cytosol for storage and luminal apolipoprotein B (apoB)-containing LDs in the ER lumen destined for VLDL secretion [122,127]. DGAT2 can also synthesize TAG using exogenous FAs and suppo
