  In humans, several different small ubiquitin-related modifier (SUMO) paralogs can be conjugated to cellular proteins. The human genome codes for five SUMO paralogs (SUMO1–5); of these, SUMO1 and the almost identical SUMO2 and SUMO3 are ubiquitously expressed. Sumoylation is executed by an enzymatic

  2020-05-06

  

  Unlike CRM1, exportins Cse1 and Xpot lack a C-extension and instead rely primarily on changes in HEAT-repeat conformation and direct Ran-cargo contacts to ensure low cargo-binding affinity in the cytosol and cooperative assembly of the exportin/Ran/cargo complex in the nucleus (Cook et al., 2005, Co

  2020-05-06

  

  The most important cytotoxic lesion formed by the nitrogen mustards is generally considered to be the DNA–DNA interstrand cross-link 12, 13. DNA–DNA interstrand cross-links are thought to exert their cytotoxic effects by inhibiting DNA duplex strand separation, progression of the byl719 fork and DN

  2020-05-06

  

  Following mutagenesis of the glucarpidase gene of Pseudomonas sp. strain RS-16 [30], approximately 73% of the clones retained enzyme activity, as indicated by the clear zones and yellow precipitate surrounding their colonies. However, there were very few that had ‘halos’ around colonies that were da

  2020-05-06

  

  Immune modulation by steroid hormones is a rather new aspect of the research on endocrine interactions in lower vertebrates (Harris and Bird, 2000). In the classical view, steroids exert their effects by binding to specific intracellular receptors that function as ligand-activated transcriptional re

  Related with the studies by Zizza et al. described above [66], work by Ward et al. [68] suggested that the C2 domain of cPLA2α, which binds to zwitterionic membranes with high affinity in a Ca2+-dependent manner, has a high membrane remodeling activity, producing dramatic changes in membrane curvatu

  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

  2020-05-06

  

  Recent reports revealed that CSE affects the endothelial cells of various tissues like kidney, liver, heart including cgrp antagonist [26,30]. The damage of brain endothelial cells enhances the progress of cognitive dysfunction due to the accumulation of toxic free bio-radicals and activation of in

  2020-05-06

  

  A structural explanation for how RBR RING1s handle their bound E2~Ubs differently from canonical RINGs has not been readily apparent. Only a few residue positions are strongly conserved in RING and RING1 domains, most of which are zinc-coordinating Cys and histidine residues. A key position in canon

  2020-05-06

  

  RING dimerization RING-type domains are found in many different structural contexts. While many exist as single-chain BKT140 (Fig. 3A), a notable feature of RING-type E3s is their tendency to form homodimers and heterodimers (Fig. 3C–F). Homodimeric RING-type E3s include cIAP, RNF4, BIRC7 (shown

  Electroencephalographs at onset ranged from hypsarrhythmia to mild abnormalities but more abnormalities in background rhythms and epileptiform activity develop over time.15, 17, 19, 48, 52, 54, 55 Early mild abnormalities that sometimes precede a diffuse encephalopathy included focal delta slowing i

  It is generally thought that the nature of a memorial and the meaning attributed to it DHT by a tourist determines, at least in part, the behaviour that is socially appropriate (Mayo, 1988). Duncan (1995) argues however, that certain places are structured in such a way that they facilitate ritual p

  It is noteworthy that epidemiological studies have demonstrated that some GAD patients have experienced anxiety symptoms in childhood and young adulthood, whereas others have developed their disorder at a later age (especially persons ≥ 50 years of age) (Hoehn-Saric et al., 1993; Le Roux et al., 200

  Introduction Prolyl hydroxylation is a widely observed post translational modification in collagen, an abundant animal protein. The high content (~13% per chain of the triple helical structure) of 4-hydroxyproline (Hyp,O) in collagen, togather with the natural abundance of collagen has led to the e

  Rice approximately covers 1% of land area of the earth and it is one of the main sources of food for billions of people [4]. One of the main agriculture industry residues is rice husk, which contains high amount of amorphous silica up to 85–95%. Rice husk ash (RHA) is a solid residue of rice husk co
