Induction operon
WebIn an operon, the DNA sequence has four major roles: it can be a regulatory gene that encodes an inhibitor/repressor protein a promoter segment where the RNA polymerase … WebThe induced phenotype can survive periods of absence of the in- ducer. This phenomenon has been attributed to an indirect feedback in which synthesis of permease, a product of the lac operon, leads to the import of more inducer, thus clicking the system at maximal expression (Wilson et al., 2007).

The arabinose operon works positively in the presence of inducer and works negatively in the absence of inducer. Catabolic Active Site In arabinose operon, an activator site is termed as CAP.
WebOur study of the HrpL regulon identified an uncharacterized, three-gene operon in Pto that is controlled by HrpL and related to the Erwinia hrp-associated systemic virulence (hsv) operon. Here, we demonstrate that the hsv operon contributes to the virulence of Pto on Arabidopsis thaliana and suppresses bacteria-induced immune responses.
