Mitochondrial RNA polymerase: dual role in transcription and replication.

Schinkel AH , Tabak HF .


Abstract
Mitochondrial RNA polymerases from humans, Xenopus laevis and Saccharomyces cerevisiae are very similar in protein composition and function. They consist of a nonspecific core RNA polymerase and a protein factor that confers promoter selectivity on the core component, and they participate in transcription as well as in DNA replication. Amino acid sequence comparisons indicate that the yeast mitochondrial core component is related to bacteriophage T3 and T7 RNA polymerases; mitochondrial and phage polymerases may therefore belong to a family of related polymerases.
