Structure and activity of the Saccharomyces cerevisiae dUTP pyrophosphatase DUT1, an essential housekeeping enzyme.
Genomes of all free-living organisms encode the enzyme dUTPase (dUTP pyrophosphatase), which plays a key role in preventing uracil incorporation into DNA. In the present paper, we describe the biochemical and structural characterization of DUT1 (Saccharomyces cerevisiae dUTPase). The hydrolysis of dUTP by DUT1 was strictly dependent on a bivalent metal cation with significant activity observed ...
متن کاملHuman somatostatin I: sequence of the cDNA.
RNA has been isolated from a human pancreatic somatostatinoma and used to prepare a cDNA library. After prescreening, clones containing somatostatin I sequences were identified by hybridization with an anglerfish somatostatin I-cloned cDNA probe. From the nucleotide sequence of two of these clones, we have deduced an essentially full-length mRNA sequence, including the preprosomatostatin coding...
متن کاملStructures of feline immunodeficiency virus dUTP pyrophosphatase and its nucleotide complexes in three crystal forms.
dUTP pyrophosphatase (dUTPase) cleaves the alpha-beta phosphodiester of dUTP to form pyrophosphate and dUMP, preventing incorporation of uracil into DNA and providing the substrate for thymine synthesis. Seven crystal structures of feline immunodeficiency virus (FIV) dUTPase in three crystal forms have been determined, including complexes with substrate (dUTP), product (dUMP) or inhibitor (dUDP...
متن کاملComplete cDNA sequence of human preceruloplasmin.
A cDNA for human ceruloplasmin (EC 1.16.3.1) was identified in a human liver cDNA library by screening with two mixtures of synthetic oligodeoxyribonucleotides that were complementary to two regions of ceruloplasmin mRNA as predicted from the amino acid sequence of plasma ceruloplasmin. The resulting clone (phCP1) contained DNA coding for amino acid residues 202-1046 of the protein, followed by...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
