The traJ gene encodes a protein required for transcription from the major transfer promoter, pY. The FinO protein is essential for effective repression, acting by binding to FinP and protecting it from RNase E degradation.
In the context of bacterial gene regulation, the traJ gene plays a crucial role in encoding a protein necessary for transcription initiation from the primary transfer promoter, pY. The FinO protein is vital for repressing this process, accomplishing this through interaction with FinP and protection against degradation by RNase E.
