Nucleotide sequence of the Aspergillus nidulans mitochondrial gene coding for the small ribosomal subunit RNA: homology to E. coli 16S rRNA.

摘要

The complete primary structure of the 1437 bp gene coding for mitochondrial 15S rRNA and its flanking regions was determined by Maxam-Gilbert sequencing of cloned HindIII fragment H3 of A. nidulans mtDNA. The gene product reveals significant homology (59%) to E. coli 16S rRNA, and the potential secondary structures of both rRNA molecules are very similar, except that the hairpin structures 7, 8 and 30 of the Brimacombe 16S rRNA model are deleted, and that two sequences of 8 and 31 nucleotides are inserted in the mitochondrial species.
