Regulation Summary Diagram: ?

Regulation summary diagram for ppdA

A ppdAB mutant does not exhibit defects in chemotaxis or flagellar motility [Park01]. Overproduction of PpdAB does not result in defects in chemotaxis or flagellar motility [Park01].

PpdA: "prepilin peptidase dependent"

Regulation has been described [Park01]. Transcription is sigmaF (FliA) regulated [Park01]. Transcription is regulated by FlhDC [Park01].
