CC   -!- FUNCTION: Usually encoded in the trnK tRNA gene intron. Probably
CC       assists in splicing its own and other chloroplast group II introns.
CC       {ECO:0000255|HAMAP-Rule:MF_01390}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the intron maturase 2 family. MatK subfamily.
