trpL promoter

The expression of the trp operon is repressed 300-fold by TrpR. TrpR binds at the trpLp promoter, possibly directly blocking binding by RNA polymerase Klig LS,1988.

The blue light sensor LovTAP is a chiameric protein that contains the TrpR DNA-binding domain, so that is expected to regulate trpL promoter as the native TrpR transcriptional regulator.
