Transcription termination factor Rho

UniProtKB accession:  P9WHF3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA-dependent ATPase activity, and release of the mRNA from the DNA template. Shows poor RNA-dependent ATP hydrolysis and inefficient DNA-RNA unwinding activities, but exhibits robust and fast transcription termination, which suggests that the transcription termination function of M.tuberculosis Rho is not correlated with its helicase/translocase activities and that these functions may not be important for its RNA release process.
