RNA editing in ATPase subunit 6 mRNAs in Oenothera mitochondria. A new termination codon shortens the reading frame by 35 amino acids.
The open reading frame encoding ATPase subunit 6 in Oenothera mitochondria is edited at 21 positions in all cDNA clones investigated. Only one of these events is silent, all others improve similarity between the homologous polypeptides of other species. The introduction of a new UAA termination codon shortens the polypeptide by 35 amino acids to a carboxy terminus conserved in other species. In one of the cDNA clones, an additional editing event was observed resulting in a premature UAA termination codon in the amino terminal region.
