Abstract

The open reading frame in the first intron of the mitochondrial gene encoding subunit I of cytochrome c oxidase encodes a maturase and stimulates homologous recombination in Escherichia coli. In this paper, we demonstrate that this intron is mobile in crosses, indicating that it also encodes an endonuclease. This is the first report on an intron which possesses mobility and acts as a maturase.
