Structural highlights
Function
[CTPB_BACSU] Involved in the signal transduction pathway leading to the proteolytic activation of the mother cell transcription factor pro-sigma-K during sporulation. The signaling serine protease CtpB triggers pro-sigma-K processing by cleaving the regulatory protein SpoIVFA and is necessary for the proper timing of sigma-K activation.[1] [2] [3]
