drosophila protein 中文意思是什麼

drosophila protein 解釋
果蠅蛋白
  • drosophila : n. （pl. drosophilas, -lae ）1. 【動物；動物學】果蠅 （＝fruit fly）。2. 〈D-〉 【動物；動物學】果蠅屬。
  • protein : n. 【化學】朊，蛋白（質）。
  1. Many organisms produce enzymes, termed photolyases, that specifically bind to these damage products and split the via a uv - a / blue light - dependent mechanism ( photoreactivation ), thereby reversing the damage. these two photolyase are specific for either cpds ( cpd photolyase ) or 6 - 4 products ( 6 - 4 photolyase ). a gene that expresses a protein with 6 - 4 photolyase activity in vitro, was recently cloned from high organisms ( arabidopsis thaliam, drosophila melanogaster, danio rerio, xenopus laevis and homo sapiens )

    目前已從高等生物擬南芥、鮐類、果蠅、人類和非洲爪蟾蜍屬中克隆到有（ 6 - 4 ）光裂合酶活性的基因，本研究從鹽生杜氏藻dunaliellasalina中克隆到（ 6 - 4 ）光裂合酶的基因，並將該基因在大腸桿菌中得以表達，這是首次在藻類中克隆到（ 6 - 4 ）光裂合酶基因，對光裂合酶的研究具有重要意義。
  2. 8 % ), which is similar to the mt protein of ostrea edulis while different from that of drosophila and mammalian ( no aromatic amino acid and histidine ). comparison of the deduced amino acid sequence of housefly mt with other species " mt showed that its identity with drosophila was highest, attain 65 % ; the different metallothioneins, within a part species of invertebrate, were 35 % - 41 % isologous ; its identi ty wi th the mt - ii of green monkey was 41 % and that with the human mt - ii was 35 %

    由擴增片段的編碼序列所推導的家蠅mt與其它生物mt比較顯示：家蠅mt氨基酸序列與果蠅（ drosophilamelanogaster ） mtn氨基酸序列的同源性最高，達到65 ；與部分無脊椎動物mt氨基酸序列的同源性在35 - 41的范圍內；與部分植物mt氨基酸序列的同源性比較結果為：同源性最高的為孢子植物墨角藻（ fucusvesiculosus ） （ 51 ） ，而最低的為種子植物鼠耳芥（ arabidopsisthalianal ） （ 35 ） ；與哺乳動物綠猴mt -的同源性達到41 ，與人類mt -的同源性為35 。
  3. Two positive clones were sequenced, and the results showed that its nuclcotidc sequence includes an open reading segment which codes for a 45 - amino acids protein and three endonuclcase sites which arc1 bgii, bamh i and bgi ii, this protein was identified as metallothionein based on its characteristic described above and its similarity ( 85 % ) to the mtn gene of drosophila : the 10 cysteine residues present occur in five pairs of cys - x - cys, x is serine, valine, ilistidine or lysine

    結果顯示：擴增的cdna片段長度為289bp ，其中含有一個編碼45個氨基酸的開放閱讀框，閱讀框所編碼的氨基酸中含有10個半胱氨酸，且在序列中均排列成cys - x - cys ，其中x為ser 、 val 、 his或lys 。這些特徵說明擴增的基因片段為家蠅mt基因序列的一部分。此基因序列片段與果蠅mtn基因序列的同源性達到85 . 0 ，擴增的基因序列中含有三個內切酶位點bg 、 bam和bg ，這一點也和果蠅mtn基因十分相似。
  4. Gfp movies : you can view these online movies of expression of green fluorescent protein ( gfp ) in a drosophila embryo
