A Mutation in the Yeast Mitochondrial Core RNA Polymerase, Rpo41, Confers Defects in Both Specificity Factor Interaction and Promoter Utilization
2003
Journal of Biological Chemistry
The yeast mitochondrial RNA polymerase (RNAP) is composed of the core RNAP, Rpo41, and the mitochondrial transcription factor, Mtf1. Both are required for mitochondrial transcription, but how the two proteins interact to create a functional, promoter-selective holoenzyme is still unknown. Rpo41 is similar to the single polypeptide bacteriophage T7RNAP, which does not require additional factors for promoter-selective initiation but whose activity is modulated during infection by association with
