E.coli turned dark green after transformation of this plasmid, it is not supposed to be so since there is no promoter upstream of the operon. We have not found the reason.

When digested with BamHI and NotI, the insert did not digest as expected, only a 2kb band (backbone) and ~6kb band were visible.

We found out that there's a point mutation in this plasmid. This mutation occurs in the Xba I restriction site which takes a lot of time for us just to digest it in order to ligase this part with our interest part.
The following figure shows the unsual gel electrophoresis result which the Xba I restriction site couldn't recognize the restriction site.
In order to correct the mutation, we then design a primer as follows:
Figure.2 Design a primer to correct the point mutation.
This primer include the precise sequence of the Xba I restriction site. We then do Polymerase Chain Reaction to extend the remaining sequence and amplify the exact plasmid that we want.
Last and the most important, we also notice something that this part is actually vioABDE instead of vioABCE.
In previous time, we failed in every attempts to clone out vioC from this part. We then decided to do DNA sequencing to make sure every single sequence is correct. Afterward, we found the exact sequence of vioABDE instead of vioABCE.
