Design Notes

The C > T point mutation occurred during cloning. It is located in the spacer region between the Fis binding sites; therefore, we believe that the mutation will not impact RE function. There is an insertion immediately before the BioBrick suffix and several bases after the distal fis binding site that should affect RE function. RE is cloned in plasmid pSB1A2.

The BioBrick prefix and suffix on this part are not wildtype but the restriction sites are still viable.

Prefix
There is no G spacer (*) between the XbaI and the RE.
Suffix
The T spacer between the RE and the SpeI site has changed to a G.
The A spacer between the SpeI and the NotI has changed to a T.
There is an extra C between the NotI site and the PstI site

Source

The Recombination Enhancer sequence from Salmonella typhimurium.
