Christianson T, et al. (1982) Transcriptional initiation and processing of the small ribosomal RNA of yeast mitochondria. J Biol Chem 257(11):6494-500
Abstract: We have identified the nucleotide at which transcription initiates on the yeast mitochondrial small (14 S) rRNA gene by sequencing of RNA labeled at the 5' initiating triphosphate with vaccinia virus guanylyltransferase [alpha-32P]GTP (in vitro capping reaction). Initiation occurs within the stem of a 12-base palindromic repeat. The initiation sequence has homology with the large (21 S) ribosomal RNA initiation sequence that has been previously determined. We have also sequenced the 5' and 3' ends of the mature 14 S rRNA after labeling with T4 polynucleotide kinase and RNA ligase, respectively. These sequences demonstrate that about 80 nucleotides are cleaved from the 5' end of a precursor to produce the mature 14 S rRNA. This cleavage is imprecise in that the processing occurs at one of five adjacent nucleotides 77 to 81 nucleotides downstream from the 5' initiation site. The 3' ends of this precursor and the mature 14 S rRNA are unique and identical.FAU - Christianson, .
