WebIntrons can be removed by three mechanisms: 1) the nuclear spliceosome, 2) self-excision, or 3) maturase enzymes. MatK is the only maturase encoded in the chloroplast of plants. Maturases are prokaryotic enzymes that bind and excise a single intron. MatK interacts with seven different introns instead of the single intron of prokaryotic maturases. WebRNases and proteases are enzymes that destroy RNAs and proteins, respectively.
