  1. The c - phycocyanin ( cpc ) operon of blue - green alga ( or cyanobacteria ) arthrospira platensis fachb341 was cloned, sequenced and characterized by using chromoseme walking method. the sequence includes cpcb gene ( 519 bp ), cpca gene ( 489 bp ), cpch gene ( 357 bp ), and upstream sequence of cpcb ( 427 bp ) and upstream sequence of cpch genes ( 184 bp ), 111 bp of phycocyanin intergenetic spacer ( pc - igs ). upstream sequence of cpcb gene was ligated into promoter - probe vector pegfp - 1 and transformed into three systems : e. coli, synechocystis pcc 6803 and a. platensis fachb341 by supersonic and electrophoresis methods

    根據genbank中報道的節旋藻藻藍蛋白基因序列設計引物,首先克隆了鈍頂節旋藻( arthrospiraplatensisfachb341 )藻藍蛋白操縱子中亞基基因、亞基基因部分序列及二者之間的間隔區序列( pc - igs )並進行序列測定,然後根據此測序結果設計引物,通過染色體步移法克隆得到藻藍蛋白操縱子長度為2086bp的基因片段,其中包括藻藍蛋白亞基基因( cpcb , 519bp ) ,亞基基因( cpca , 489bp ) ,連接蛋白h基因( cpch , 357bp ) ,亞基基因上游啟動子序列( 427bp )以及各基因之間的間隔區( pc - igs , 111bp ; cpch與cpca間隔區, 184bp ) 。
  2. Escherichia coli promoter, which could initiate transcription of a gene, was mainly consisted of two conserved sequences, - 10 box and - 35 box, and spacer between them, whose length is changeable

    大腸桿菌啟動子能起始基因的轉錄,它主要由兩段比較保守的序列片斷- 10框、 - 35框和它們之間一段長度可變的堿基序列組成。
