CC   -!- FUNCTION: Function in mitochondrial RNA splicing in the excision of
CC       mitochondrial group I introns aI1 and aI5 beta from COX1 and bI3 from
CC       COB transcripts and thus would be involved in obtaining the correct
CC       structure of the intron, to allow the RNA catalyzed reactions to occur.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000305}.
