  Results Discussion The ubiquitin system has in recent years become an exciting area for drug discovery (Cohen and Tcherpakov, 2010), as multiple enzymatic steps within the ubiquitylation process are druggable. The potential of targeting the ubiquitin-proteasome pathway was first demonstrated i

  Recent studies have also uncovered additional roles for E2 enzymes and E2~Ub conjugates in modulating the activity of deubiquitinating enzymes (DUBs), such as OTUB1 (Juang et al., 2012, Wiener et al., 2013, Wiener et al., 2012). Interestingly, OTUB1 has also been shown to associate and modulate the

  Despite the fact that the precise relevance of Ube2E self-ubiquitination in vivo is still elusive, findings of Sarkari et al. do establish Ube2E1 ubiquitination in TNKS 22 receptor [36]. In vivo self-ubiquitination of Ube2E1 is further supported by the high-throughput study aimed to identify all ub

  2019-10-21

  

  Cellular immune responses, such as phagocytosis and apoptosis, are very important processes to eradicate the invading pathogens and reduce concomitant host damage. And all of these processes are fine-tuned by the ubiquitin system (Li et al., 2016). Phagocytosis is a major mechanism of cellular immun

  2019-10-21

  

  Initially, the E1 uses ATP to activate the C-terminal glycine residue of ubiquitin prior to ligation. In the first step of E1 activation, the E1 catalyzes the adenylation of ubiquitin and pyrophosphate (PPi) release. In the second step, the E1 releases adenosine monophosphate (AMP) and a thioester b

  Diabetic retinopathy is a chronic inflammatory disease. Local inflammation plays a pivotal role in the pathological development and progression of this disease [24]. In addition to TNF-α, several other cytokines, chemokines, and other factors such as IL-1β, IL-6, and C-reactive protein have been ind

  In essential hypertensive patients, it is known that the CB is enlarged (Habeck, 1986). In addition to morphological changes in the CB, hyperventilation was reported in essential hypertensive patients at resting conditions (Trzebski et al., 1982). Furthermore, CB is innervated by postganglionic symp

  Materials and methods Results Artemis has been reported to possess 5′–3′ exonuclease activity in vitro on ssDNA, as well as DNA-PK-dependent endonuclease activity on single-strand overhang and hairpin DNA structures [11]. However, enzymes within the metallo-β-lactamase family typically contain

  In the case of high-fidelity polymerases, we propose that water is used to achieve negative selection against nucleotide binding. With specialized DNA polymerases, we propose that nucleobase desolvation plays a different yet important role in allowing these enzymes to replicate damaged DNA. In this

  Introduction Acinetobacter baumannii is a gram-negative opportunistic pathogen that causes nosocomial infections including pneumonia and bloodstream infections which is associated with an increased mortality and multi-drug resistance [[1], [2], [3]]. A. baumannii was rated as one of the critical

  Pyrazolopyrimidines are bioisostere of purine exhibit promising antitumor activity by competitively binding to the ATP active site of different kinase SB1518 pathway [16,17]. Several compounds of this family were found to induce apoptosis and/or reduce cell proliferation in various solid tumour and

  Cryoprotectant equilibration and the response to ice concentrated media are the two facets of cellular cryobiological protocols most commonly covered by mathematical modeling. In these models, SecinH3 are typically assumed to have uniform, spatially independent extracellular concentrations and temp

  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

  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
