Crystal structure of human mitochondrial mTERF in complex with a 15-mer DNA encompassing the tRNALeu(UUR) binding sequence

Template:ABSTRACT PUBMED 20543826

Function

[MTERF_HUMAN] Transcription termination factor. Binds to a 28 bp region within the tRNA(Leu(uur)) gene at a position immediately adjacent to and downstream of the 16S rRNA gene; this region comprises a tridecamer sequence critical for directing accurate termination. Binds DNA along the major grove and promotes DNA bending and partial unwinding. Promotes base flipping. Probably requires one or more components for termination activity.^[1]
