Usage and Biology

FeaR is an AraC family regulator that activates transcription of the tynA and feaB genes in Escherichia coli.feaR-A81L was identified as PEA-specific variantss,with 580-fold induction.

Functional Verification

In our project, FeaR-A81L binds to phenylacetaldehyde (PAG) and induces the expression from PtynA.
