  TgTCEA from petals (TgTCEA1) and TgTCEB from pollen grains (TgTCEB1) were used throughout the study. The recombinant enzymes were expressed in , and purified as the His-tag-free forms as described previously., Enzyme reactions were performed at 4 mM substrates under the same conditions as described

  Regulation of p53 via the ubiquitin-proteasome pathway Studies into regulation of p53 via PTM processes that involve phosphorylation, acetylation, ubiquitination, SUMOylation, neddylation, and methylation are being increasingly reported [23], [24]. Phosphorylation and acetylation of p53 stimulate

  GPCRs form heterotetramers In addition to homodimers and heterodimers, for several family A receptor heteromers, experimental evidence supports the presence of higher order rearrangements as tetrameric structures, comprised of two different homodimers, each able to signal with its preferred G pro

  Increasing evidence suggests that normal vaginal delivery is a natural inflammatory process which results in increased levels of cytokines like Interleukin-6 (IL-6), Interleukin-8 (IL-8) in maternal and cord blood plasma [10]. Increased levels IL-6 and IL-8 have been reported in the amniotic fluid o

  While previously reported optimizations on TNF-alpha, recombinant rat protein focused on the phenyl ring A () and substituents on isoxazole ring, other alternatives to replace isoxazole ring were never explored. Herein, we propose to replace the isoxazole with its bioisosteric substituted phenyl r

  2021-08-11

  

  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 ac

  From an industrial perspective, the low turnover numbers and limited substrate scope of α-KG halogenases still represents a significant challenge. However, in light of the fact that currently no chemical processes are available for the selective halogenation of aliphatic carbon centers in complex mo

  Our previous work has demonstrated that two glutamate residues (Glu-305 and Glu-331 in murine and human TPP II) in the active site are important for exopeptidase activity in mTPP II [17]. At least one of these, Glu-331, seems to form a salt bridge to the N-terminal amino group of the substrate, posi

  On the other hand, the interaction of the Kaempferia parviflora extract with CYP3A was uncompetitive with a low Vmax value. In the in vivo study, the Kaempferia parviflora extract did not interfere with CYP3A activity throughout the entire duration of treatment. This is fortunate as CYP3A isoforms a

  The relatively less well-studied encodes the E2 type SUMO-conjugating enzyme. In plants, the SCE family members play roles in abiotic stress responses. An E2 enzyme, SaSce9, from plays roles in salinity and drought stress responses (). Furthermore, SCE can respond to heat stress in rice (). Howeve

  The E1 enzyme is the apex for downstream enzymatic cascades and signaling pathways mediated by Ub and Ub-like proteins (Ubls) (Pickart, 2001). Studying characteristics of E1 and its catalytic functions may throw light to the role of ubiquitination in cell development. All known eukaryotic E1 are mon

  Common features of TdT, pol μ and pol λ TdT, pol μ and pol λ remain in a closed conformation throughout their catalytic cycle, contrary to pol β [24•, 53, 54•]. One possible explanation for this observation is that they have traded fidelity (which requires open-to-closed transition) for a very t

  During the past three decades, platinum-based DNA-alkylating agents have been employed in the treatment of various cancers [14]. Oxaliplatin is currently used as a first-line treatment for colorectal cancer (CRC) [15]. Unfortunately, a large portion of CRC patients receiving oxaliplatin-based chemot

  In the present study, we used a new luminescent method to measure CYP activity with Luciferin-ME as a substrate which is used for wide ranges of mammalian CYPs, including CYP1A2, CYP2C8, CYP2C9, CYP2J2, CYP4A11, and CYP4F3B. As a result, no significant modulations of CYP activities in B[a]P exposure
