RT   "Phylogenetic analysis of Picea species based on chloroplast and
RT   mitochondrial gene sequences.";
RL   Submitted (MAY-2001) to the EMBL/GenBank/DDBJ databases.
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.
