Group I introns fold into characteristic secondary and tertiary structures. In a Mg2+-dependent reaction initiated by a guanosine cofactor, group I ribozymes catalyse their own excision from the primary transcript. In addition, group I introns often contain an open reading frame that assists the intron in its own mobility.
