Intron-encoded endonuclease I-SceI is a specific type of enzyme that belongs to a class of proteins known as homing endonucleases. It is derived from the mitochondrial DNA of certain species of fungi, particularly the yeast *Saccharomyces cerevisiae* (baker's yeast), where it is encoded within an intron of a larger gene.
