MUTAGENIC PRIMERS

The native crtI sequence contains two internal PstI sites. These were removed by MABEL site directed mutagenesis by Douglas Leslie (Honours project, 2008). Initially mutagenesis by megaprimer PCR was attempted (see iGEM 2007 lab book page 57, also file 'mutagenicPrimersForcrtI20aug07.doc'), using primers crtImut1 and crtImut2, but this was not successful, so primers crtImutf1 and crtImutf2 were ordered so that the MABEL protocol (invented for this purpose) could be used instead.The mutagenic primers were as follows:

   * crtImut1: gct tct cca tgc ttg cag ttt cgc cag
   * crtImut2: cat gcg ctt agt ttg cag ttt gtt gg
   * crtImutf1: gtt tac agt aag gtt gcc : none, no, 51.81 C.
   * crtImutf2: agt aac tct ctg ttt gtg c : very weak, no, 51.46 C

In both cases, the PstI site CTGCAG was converted to CTGCAA, a silent mutation.
