random mutagenesis 解釋
無規突變誘變
  • random : n 〈罕用語〉胡亂行為,偶然的[隨便的]行動[過程]。adj 1 任意的,胡亂的,隨便的;(話等)信口亂說的...
  • mutagenesis : n. 突變。
  1. Dominant negative alleles of gpil7p were produced by random pcr mutagenesis of three conserved fragments of gpi17p : 1 ) having generated the plasmid library which contains 100000 plasmids harboring gpi17 mutants then screened from 8000 clones, we got 25 strong and 3 very strong dominant negative alleles

    對gpi17p可能的三個保守區進行了pcr隨機誘變,並最終獲得顯性負性等位基因: 1 )組建了gpi17p突變體質粒庫,其所含質粒數約為100000 。
  2. A mutant library of xanthomonas campestris pv. campestris ( hereafter xcc ) strain 8004 with 17820 clones was constructed by random transposon tn5gwsa5 mutagenesis, which cover 1800 predicted orfs of xcc genome

    用轉座子tn5gusa5誘變野油菜黃單胞菌( xanthomonascampestrispv . campestris以下簡稱xcc ) ,構建了xcc8004tn5gusa5插入突變體庫。
  3. The mutant pel - d92l was expressed in pichia pastoris gs115, sds - page detection showed that the expression product pel - d92l - gs is different from pel - gs, and its " yield decreased dramatically, the themostability of pel - d92l - gs is also different from the pel - gs, but their optimum temperatures are same. 3. directed evolution of pel through random mutagenesis mutagenesis pcr carried out in error - prone conditions was used on the vector psk - pel, using the oligos " beginning " and " end ", homologous to the 5 ' and to the 3 " ends of the gene of pel respectively

    三、 pel基因的隨機誘變用易錯pcr方法對pel基因進行隨機誘變, pcr產物與ppic3 . 5k連接,轉化大腸桿菌,獲得的混合質粒電轉化畢赤酵母gs115 , omm平板篩選適于低溫或對熱穩定的重組子,篩選獲得一株最活反應溫度、熱穩定性、發酵酶活均有提高的突變體pel - ep5 - gs ,其最活反應溫度為45 ,比野生型高出5 ; 40處理30min殘留活性為56 ,大大高於野生型的6 ;初始ph7 . 3528條件下培養72h ,發酵上清酶活為325u / ml 。
