  In this study, using REMD with the crystal environment, we investigate the effect of cryo-cooling on the crystal structure of Escherichia coli DHFR. DHFR is an important model enzyme (for review, see, e.g., (30)), and has been studied for decades (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43).

  Recently, several Pt(IV) complexes as prodrugs have been designed and studied to enhance anti-tumor efficacy of traditional Pt(II) drugs, improving their cellular uptake and blood-circulation time [26], [27], [28], [29]. Compared with their Pt(II) counterparts, six-coordinated Pt(IV) complexes with

  Materials and methods Results Discussion The incretin hormones potently stimulate insulin secretion, and it is generally assumed that this is mediated by an endocrine mechanism such that GIP and GLP-1 through the circulation reach the islet beta 9620 to stimulate their secretion. However,

  Electron transfer pathway Intramolecular (or inter-domain) electron transfer (IET) in CDH has been studied in much depth [], and similar IET occurs in CcPDH, from the PQQ cofactor in the AA12 domain to the heme b in the AA8 domain. When two kinds of electron acceptors are used for measuring enzym

  As we all known, hypoxia is a hallmark of tumour microenvironment, which is a key regulator of tumour growth and metastasis [4]. Hypoxia meditates a series of cellular responses including angiogenesis by activating transcriptional factor hypoxia inducible factor (HIF), which is consist of an obligat

  Flavonoids are most common and widely distributed group of natural phenolic compounds synthesized by plants that have varied effects on mammalian cell systems (Kumar and Pandey, 2013). Several studies demonstrate that flavonoids might be potent inhibitors of several protein kinases involved in vario

  2020-02-05

  

  The work described by Dong, Groves, and co-workers (11) tested the hypothesis that neural stem cell development is sensitive to the clustering and mechanical state of the EphB4:ephrin-B2 receptor-ligand complex. They show that the quality of ephrin-B2-ligand signaling depends on its biophysical stat

  2020-02-05

  

  Epac proteins consist of a carboxyl-terminal catalytic region and an amino-terminal regulatory region, which harbors one cAMP-binding domain in Epac1 and two in Epac2 [22], [32], [51]. In the absence of cAMP, the regulatory region covers the CDC25-homology domain and autoinhibits Epac\'s enzymatic a

  Elevated DPP-4 activity has been strongly associated with diabetes mellitus, IR (Röhrborn et al., 2015), metabolic syndrome (Lamers et al., 2011) and inflammation (Zhong et al., 2015). However, report has it that GC exposure increases DPP-4activity in thymocyte homogenates (Kraml et al., 2003) but t

  Our finding that the ATRX-DAXX-H3.3 complex promotes a form of HR is likely to have important implications for our understanding of the ALT recombination process that takes place at telomeres. We were surprised to observe that ATRX promotes a form of HR, since loss of the ATRX-DAXX-H3.3 complex is n

  Our previous studies have demonstrated that the DDR2 discoidin domain fully contains the binding site(s) for the fibrillar collagens I and II (Leitinger, 2003, Leitinger et al., 2004). The binding site for collagen I was mapped to three spatially adjacent surface loops within the DDR2 discoidin doma

  During the past decades HT had been widely prescribed with the expectation of both osteoporosis and cardiovascular disease prevention. The results of the Women\'s Health Initiative (WHI) trial, however, indicated that long-term HT use is associated with a small but significant increase of cardiovasc

  Halogenases Enzymatic C–H activation leading to halogenation is another emerging area in biocatalysis [55,56]. Incorporation of halogen atoms during medicinal chemistry eff ;orts is a well-established practice, presenting an effective means to control the molecule’s bioactivity and physicochemical

  The structure of the HOIP RBR–LDD module bound to UbcH5~Ub reveals insights into an activated HOIP component [47]. Contacts between the E2~Ub and the non-cognate RBR module in the crystal suggest how a structure in which the active sites of the E2 and the E3 are in close proximity might look. In thi

  The majority of APC/C subunits form a giant scaffold, which was originally named the arc lamp, based on its shape when viewing APC/C from one side (Figure 1 and Box 1) [24]. The scaffold consists of two modules: the TPR lobe resembles the curved post and lamp, and the platform resembles the tak tak
