Crystal structure of human mitochondrial mTERF fragment (aa 99-399) in complex with a 12-mer DNA encompassing the tRNALeu(UUR) binding sequence

Structural highlights

3n7q is a 3 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

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]

Publication Abstract from PubMed

The regulation of mitochondrial DNA (mtDNA) processes is slowly being characterized at a structural level. We present here crystal structures of human mitochondrial regulator mTERF, a transcription termination factor also implicated in replication pausing, in complex with double-stranded DNA oligonucleotides containing the tRNA(Leu)(UUR) gene sequence. mTERF comprises nine left-handed helical tandem repeats that form a left-handed superhelix, the Zurdo domain.

Human mitochondrial mTERF wraps around DNA through a left-handed superhelical tandem repeat.,Jimenez-Menendez N, Fernandez-Millan P, Rubio-Cosials A, Arnan C, Montoya J, Jacobs HT, Bernado P, Coll M, Uson I, Sola M Nat Struct Mol Biol. 2010 Jul;17(7):891-3. Epub 2010 Jun 13. PMID:20543826^[2]
