The Avi.groEL intron of Azotobacter vinelandii, which interrupts the termination codon of the groEL gene, is shown to belong to a monophyletic subset of bacterial group II introns that share a large insertion at their 5' extremity and a peculiar genetic localization. Some of these introns are inserted within, right next to, or very close to, a stop codon while others are located immediately 3' of, or close to, an initiation codon. After subgroup IIC introns, which target rho-independent… CONTINUE READING
