Oleic acid inducer
This is a promoter module that can respond to oleic acid induction. And it has different response intensities for different oleic acid concentrations.
Usage and Biology
The FadR protein expressed by the FadR gene can bind to the operator FadO following the FadBA promoter, which inhibits the initiation of FadBA. However, oleoyl CoA metabolized from oleic acid can relieve this inhibition and promote the expression of FadBA promoter. This allows it to be induced by oleic acid for expression. In practical applications, we can change the number and position of FadO operators to change their response threshold to oleic acid to achieve more precise regulatory effects.
Characterization
In order to characterize the oleic acid inducer, we added mRFP after the oleic acid inducer for characterization, and we validated the response of the oleic acid inducer to gradient oleic acid by inducing the initiation of the oleic acid promoter under both aerobic and anaerobic conditions, as well as the operability of the part under anaerobic conditions.
