CC   -!- FUNCTION: Usually encoded in the trnK tRNA gene intron. Its retention
CC       as a freestanding gene in this organism suggests it acts in trans to
CC       assist in splicing chloroplast group II introns.
CC   -!- SUBCELLULAR LOCATION: Plastid.
CC   -!- SIMILARITY: Belongs to the intron maturase 2 family. MatK subfamily.
CC       {ECO:0000305}.
