Abstract

A mitochondrial polymerase The transcription of the mitochondrial genome is carried out by a single-subunit RNA polymerase (mtRNAP), which is distantly related to the RNAP of bacteriophage T7. Unlike T7 RNAP, the mtRNAP requires additional transcription factors (TFAM and TFB2M) for transcription initiation. The crystal structure of human mtRNAP has now been determined, revealing novel domains and mechanistic adaptations that explain the requirement for TFAM and TFB2M. These findings provide insights into the evolution of polymerases from simple self-sufficient enzymes to large multi-subunit complexes.
