Yeast Mitochondrial Transcription Factor Mtf1 Determines the Precision of Promoter-Directed Initiation of RNA Polymerase Rpo41

Comparisons of promoter strength and structure.
(A). Sequences and structures of the 65-bp constructs contain a linear promoter and a pre-melted region with or without 14S rRNA promoter. (B-D). transcripts yielded from the ab0ove constructs using Rpo41 wild-type or ΔN160 (0.5 μM) in the absence or presence of Mtf1 (2.5 μM), labeled with [γ-32P]GTP, [γ-32P]ATP, and [α-32P]ATP, respectively.
