  2019-08-01

  

  An Ubl modification requires several steps that are catalyzed by three enzymes, referred to as E1 (activating enzyme), E2 (conjugation enzyme), and E3 (ligase). The SUMO E1 is a heterodimer of SAE1 and Uba2 (also known as SAE2). In brief, an Ubl is first activated by E1 through ATP hydrolysis and fo

• Enzyme activity loss during the hydrolysis

  2019-08-01

  

  Enzyme activity loss during the hydrolysis process has traditionally been associated with thermal, mechanical, and/or chemical mechanisms (Okino et al., 2013, Ye et al., 2012, Zhang et al., 2010). Due to the recent discovery of enzyme activity loss due to interaction with substrate, it is important

  2019-08-01

  

  EBI2 and its ligand(s) EBI2 was found in a screen of upregulated genes in human B cells upon infection with EBV [1]. EBI2 is a G-protein (Gαi type) coupled receptor [2] but as long as 18 years after its discovery the nature of its ligand remained undisclosed. With the help of transfected cell lines

  Alpha-SYN has no direct effect on forskolin-induced CREB phosphorylation, but rather blocks the stimulation of CRE-mediated transcription in the nucleus. Previously we suggested that α-SYN can enter the nucleus and is present in both cytosolic and nuclear fractions without direct interaction between

  2019-08-01

  

  The related catalytic regions of the human DNA ligases contain three domains, a DNA binding domain (DBD), a nucleotidyl transferase domain (NTase) and an oligonucleotide/oligosaccharide-fold binding domain (OBD) (Ellenberger and Tomkinson, 2008). Similar to DNA ligase I, the DNA ligase III polypep

  Expression of both CH25H and CYP7B1 by lymphoid stromal EI1 solubility is required for the synthesis of 7α,25-OHC in lymphoid tissues and the correct positioning of B cells. Production of EBI2 ligand by hematopoietically derived cells appears limited [24] but may occur under some circumstances, giv

  RING-type E3s and their substrates There is enormous diversity in substrate ubiquitination and its regulation, as the targets of RING-type E3s are incredibly varied. RING-type E3s are implicated as tumor suppressors, oncogenes, and mediators of endocytosis, and play critical roles in complex mul

  Materials and methods Results In the leaves of the studied varieties, one to three nucleoli per nucleus were observed (Fig. 1a), except for the variety Bastardo were a maximum of two nucleoli per nucleus were detected. In the root-tip cells, most of the varieties presented one to three nucleo

  What does this mean for cancer therapy? We found that components of the de novo pyrimidine synthesis pathway rarely mutate in cancer, clearly showing its importance. In our experimental models, the pathway, including DHODH itself, was primed to respond when the block in CoQ redox-cycling was removed

  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

  An important question is to what extent any differences in radioligand characteristics may have contributed to discrepancies between studies. Two studies on schizophrenia addressed this question directly by using [11C]SCH 23390 and [11C]NCC 112 in the same individuals, not finding any differences be

  The evaluation of internal exposure in workers with omethoate is challenging. Unfortunately, OPs are metabolized and excreted quickly in the urine usually within 24–48 h of exposure, and the variation in metabolic rates exists. Many factors influence daily urinary output, such as salt intake, urea a

  Recent studies have reported that miR-454 plays an important role in various cellular processes and diseases, such as inflammation, infection, osteogenic differentiation, and cancers [25,27,29,30]. Multiple evidence has documented that miR-454 promotes the proliferation, migration and invasion, and

  Discussion The N-terminal domain of DDRs has long been recognized as a member of the DS superfamily (Johnson et al., 1993, Karn et al., 1993), and its role in collagen binding is understood in atomic detail (Carafoli et al., 2009, Ichikawa et al., 2007). Our crystal structure shows that the secon
