  2021-06-04

  

  P4H is a nonheme iron(II) dioxygenase that uses O2 and α-ketoglutarate as co-substrates (Fig. 1A). The three-dimensional structure of mammalian P4H is unknown. We reasoned that an electrophilic analog of α-ketoglutarate could serve as an irreversible inhibitor of the enzyme and, hence, a useful prob

  2021-06-04

  

  We have previously reported that CK2 is downregulated in senescent human lung fibroblast IMR-90 cells, aged rat tissues, and aging nematodes [17,18]. CK2 downregulation induces cellular senescence via the PI3K-AKT-mTOR-reactive oxygen species-p53-p21Cip1/WAF1 pathway in human cells [[19], [20], [21]

  2021-06-04

  

  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

  2021-06-04

  

  Enzyme mimics belong to a type of rising catalysts which show the similar function with their corresponding natural enzymes [20], [21], [22], [23], [24], [25], [26], [27], although their structures are different from natural enzymes. In the area of prodrug activation, the widely-used enzyme mimics a

  2021-06-04

  

  Host cell invasion by tachyzoites relies on the secretion of numerous secretory proteins and plays a crucial role in maintaining infection [6]. ESA released by tachyzoites are highly immunogenic and induce either antibody-dependent or cell-mediated protective immunity [11], [44], [45]. To investigat

  While oxysterols were most extensively studied for its potent ability to mediate feedback regulation of cholesterol biosynthesis, some early investigations showed that the enzymes involved in its syntheses were highly upregulated in macrophages and dendritic cells—an indication of possible roles in

  2021-06-04

  

  RING dimerization RING-type domains are found in many different structural contexts. While many exist as single-chain NB-598 hydrochloride synthesis (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

  2021-06-04

  

  The Inhibitor of APoptosis (IAP) proteins were first identified as gene products of baculovirus that inhibited apoptosis of infected insect Fructose mg (Clem et al., 1991, Crook et al., 1993). Subsequently, the mammalian IAP family was identified (Rothe et al., 1995, Uren et al., 1996). All members

  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  To determine whether the same concentration of humic VX-11e causes changes in PCR efficiency, we performed another experiment in which the humic acid was added to the PCR mix after bisulfite conversion. All samples that were amplified in the presence of humic acid (thick lines) show a decrease in P

  Besides degrading cholesterol, the cholesterol degradation pathway also offers a route to obtain useful starting materials for the production of steroid drugs and hormones. Indeed, steroids are among the most marketed pharmaceuticals with about 300 approved steroid drugs [15] and a worldwide market

  At the cellular level, TGF-β1 has been involved in the formation of invadosomes (Mandal et al., 2008, Varon et al., 2006). Invadosomes are actin-based structures involved in matrix degradation and cell invasion through metalloproteinases (MMP) activity (Linder et al., 2011). Invadosomes, constitutiv

  Proteins that associate to PCNA are characterized by having conserved motifs as the PCNA-interacting protein (PIP) motif [29,30], its variant PIP-like motif [31,32] or the APIM motif (Alk B homologue 2 PCNA interacting motif [33,34]); for instance, p21 contains a PIP motif [30], and DNA polymerases
