RT   "Analysis of the Amborella trichopoda chloroplast genome sequence suggests
RT   that Amborella is not a basal angiosperm.";
RL   Mol. Biol. Evol. 20:1499-1505(2003).
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.
CC       {ECO:0000255|HAMAP-Rule:MF_01390}.
