Intron - an overview ScienceDirect Topics

WebGroup II introns use intron-encoded reverse transcriptase, maturase and DNA endonuclease activities for site-specific insertion into DNA. Although this type of intron is self splicing in vitro they require a maturase protein for splicing in vivo. It has been shown that a specific region of the aI2 intron is needed for the maturase function. WebGroup II introns are a large class of self-catalytic ribozymes and mobile genetic elements found within the genes of all three domains of life.Ribozyme activity (e.g., self-splicing) can occur under high-salt conditions in vitro.However, assistance from proteins is required for in vivo splicing.
