【摘要】:利用同源性搜索,在中華按蚊(Anopheles sinensis)基因組中鑒定出1條乙酰膽堿酯酶(Ace)家族序列,命名為AsAce1(GenBank登錄號:KU900233)。該基因序列的全長為5 592bp,編碼區(qū)序列長度為2 253bp,編碼750個氨基酸。在理化性質(zhì)、二級結(jié)構(gòu)、三級結(jié)構(gòu)、系統(tǒng)發(fā)生、基因結(jié)構(gòu)等方面對該基因及所編碼蛋白進(jìn)行了預(yù)測和分析。結(jié)果表明AsAce1蛋白在按蚊中具有很高的保守性;該蛋白是親水性蛋白,分子量、等電點分別為82.41kD,5.92,二級結(jié)構(gòu)主要以不規(guī)則卷曲為主,無跨膜結(jié)構(gòu)域和信號肽;亞細(xì)胞定位顯示該蛋白位于細(xì)胞質(zhì)中;基因結(jié)構(gòu)為兩種相位(1位和2位內(nèi)含子)。研究結(jié)果為AsAce1基因生物學(xué)功能的挖掘奠定了理論基礎(chǔ)。
[Abstract]:By homology search, a (Ace) family of acetylcholinesterase was identified from the (Anopheles sinensis) genome of Anopheles sinensis and named AsAce1 (GenBank accession number: KU900233). The total length of the gene was 5592 BP and the length of coding region was 2253 BP, encoding 750 amino acids. In the aspects of physicochemical properties, secondary structure, tertiary structure, phylogeny and gene structure, the gene and its encoded protein were predicted and analyzed. The results showed that AsAce1 protein was highly conserved in Anopheles japonicus and was hydrophilic protein with molecular weight and isoelectric point of 82.41 kD 5.92. The secondary structure was mainly irregularly curled with no transmembrane domain and signal peptide. The subcellular localization showed that the protein was located in the cytoplasm and the gene structure was in two phases (1 and 2 introns). The results laid a theoretical foundation for the discovery of biological functions of AsAce1 gene.
