We have introduced aid gene to E. coli and measured level of mutations using rifampicin test. It works. The results are here:

We have tested this part in conjunction with T7 polymerase and target gene (lacZ) under T7 promoter in Top10 strain. Although we have obtained white colonies in various experimental setups ([http://2008.igem.org/wiki/index.php?title=Team:Warsaw/JSTest&num=7&arg0=2_June_2008&arg1=5_June_2008&arg2=6_June_2008&arg3=11_June_2008&arg4=12_June_2008&arg5=13_June_2008&arg6=16_June_2008&name=Blue/white%20and%20rifampicin%20test%20%231 #1] and [http://2008.igem.org/wiki/index.php?title=Team:Warsaw/JSTest&num=4&arg0=17_June_2008&arg1=18_June_2008&arg2=19_June_2008&arg3=23_June_2008&name=Blue/white%20and%20rifampicin%20test%20%232 #2]) sequencing revealed no mutations in target region (T7 promoter or lacZ ORF). We have [http://2008.igem.org/wiki/index.php?title=Team:Warsaw/JSTest&num=4&arg0=29_August_2008&arg1=30_August_2008&arg2=31_August_2008&arg3=1_September_2008&name=Blue-white%20screening%20and%20rifampicin%20test%20in%20GM2163 repeated] this experiment in GM2163 strain which is incapable of MutHLS mediated DNA repair due to lack of Dam and Dcm methyltransferases and obtained heritable white phenotype at high frequencies. Unfortunately we have no sequencing data to prove that mutations really occurred. |

We tried to express this RFC10 part cloned in an expression vector with arabinose promotor and a RBS. No mutation was detected on a target plasmid and no AID overexpression could be seen on an SDS gel. We assume that the distance from the RBS to the ATG start codon is suboptimal due to the distance from the XbaI site to the ATG. We suggest to clone this part as an RFC10 expression part. |
