Protein attributes

Sequence length504 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Usually encoded in the trnK tRNA gene intron. Probably assists in splicing its own and other chloroplast group II introns By similarity. HAMAP-Rule MF_01390

Subcellular location

Plastidchloroplast HAMAP-Rule MF_01390.

Sequence similarities

Belongs to the intron maturase 2 family. MatK subfamily.

Sequence caution

The sequence BAA84366.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
