Activation of the trpBA promoter of Pseudomonas aeruginosa by TrpI protein in vitro.
-
Purified TrpI with InGP activates trpBA and represses trpI transcription in vitro.
"purified TrpI protein and indoleglycerol phosphate (InGP) activate transcription initiation at the trpBA promoter (trpPB) and repress initiation at the trpI promoter (trpPI)"
The roles of indoleglycerol phosphate and the TrpI protein in the expression of trpBA from Pseudomonas aeruginosa.
-
TrpI binds site I without InGP and sites I and II with InGP.
"in the absence of InGP, the binding site of TrpI is located in the -52 to -77 region of the trpBA promoter; in the presence of InGP, the binding region is extended to the -32 region"
