WebThe first intron to be identified as distinct from group I was the ai5γ group IIB intron, which was isolated in 1986 from a pre-mRNA transcript of the oxi 3 mitochondrial gene of Saccharomyces cerevisiae. A subset of group II introns encode essential splicing proteins, known as intron-encoded proteins or IEPs, in intronic ORFs. The length of ...
