RT   "The chloroplast genome from a lycophyte (microphyllophyte), Selaginella
RT   uncinata, has a unique inversion, transpositions and many gene losses.";
RL   J. Plant Res. 120:281-290(2007).
CC   -!- FUNCTION: Usually encoded in the trnK tRNA gene intron. Probably
CC       assists in splicing its own and other chloroplast group II introns (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the intron maturase 2 family. MatK subfamily.
CC       {ECO:0000305}.
