Name  Transcription-repair coupling factor Short Name  Mfd
Type  Family Description  The bacterial transcription-repair coupling factor (Mfd) binds to stalled transcription elongation complexes in vitro and catalyses their dissociation from template DNA in an ATP-dependent manner []. A lesion in the template strand blocks the RNA polymerase complex (RNAP). The RNAP-DNA-RNA complex is specifically recognised by Mdf, which releases RNAP and the truncated transcript. Mfd displaces RNAP at the lesion site by pushing the polymerase forward [], allowing the lesion to be accessed by repair proteins []. Mfd contains superfamily II helicase motifs which are essential for the RNAP displacement activity of Mfd [], but does not possess conventional strand-separating helicase activity [].
