Description
This part contains XylE coding on the 3' strand. In many biological settings there may be read-through caused by upstream elements, however this can often be unidirectional. In settings where readthrough from 5' direction is expected to be much stronger than 3' direction, it may is advantageous to use 3' coding sequence instead of traditional 5'.
For the purposes of characterisation, the part was made on the minus strand to reduce background transcription. Read-through from 5' direction may provide an additional benefit. Low quantities of anti-sence RNA may be produced as the result of 5' readthrough, which may in turn reduce basal expression sometimes seen in LacI systems.
