Critical base substitutions that affect the splicing and/or homing activities of the group I intron bi2 of yeast mitochondria.

Molecular & general genetics : MGG - 1 Sept 2000

Szczepanek T, Jamoussi K, Lazowska J

Abstract excerpt

The second intron (bi2) of the cyt b gene from related Saccharomyces species has an extraordinarily conserved sequence and can have different functions in wild-type cells. The protein encoded by the S. cerevisiae intron functions as a maturase to promote intron splicing, while the homologous S. capensis intron encodes a bifunctional protein that acts both as a maturase and as a homing endonuclease (I-ScaI)...
