Design Notes

In the previous literature，most of research work on pdu BMC(or pdu MCP) focus on Citrobacter Freundii and Salmonella enterica. Taking all of the factors together, we choose Citrobacter Freundii as the orgin of gene in our project. Because the whole genome of Citrobacter Freundii has not been decoded yet, we use the reference sequence sent to NCBI by Martin J.Warren group(GenBank: AM498294.1). In order to make the part Compatiblee with the BBF RFC10&RFC53(A noval BioBrick assembly standard designed to facilitate protein fusion) for the following experiment, we serached the restriction enzyme site EcoRI, XbaI, SpeI, PstI, EarI, SacI ,SapI and BglII site in pduTUV(18502-19813). Luckily, none of these was found in pduAB.

We got the Citrobacter Freundii from NBRC(NBRC NO.12681). We isolate the whole genome of Citrobacter Freundii. Then we use this genoe as template to get pduTUV gene by PCR. Here is the primer we used in pduTUV PCR.

forward primer:

5'-GTTT GAATTCGCGGCCGCTTCTAGAG CTGAGCAATCCATCACGGTAATAAG-3'

reverse primer

5'-GTTT ACTAGTA TTATTTTGTGAGACAGGAAGATTCCTTTGCATTC-3'

The sequence results of pduTUV are different from the sequence we found on GeneBank. Some silent mutation locate in the sequence with no special spacial rule. We suspect that the strain we used is not same with the papar, maybe even belong to different strain of Citrobacter Freundii. However the proterin sequence alignment between the result of Martin J.Warren group, the proterin sequence of pduAB in Salmonella enterica and ours shows that the 'mutation' locate in the nonconserved site. Thus we decide to continue our experement with the gene pduTUV.
