Putative secondary structure drawing of EV-cox1 intron (Exechonella vieirai). The intron-encoded protein open-reading frame (ORF) was excised prior to folding. Domains V and VI and intron-binding site IBS1 and corresponding exon-binding site EBS1 are indicated. Less certain IBS2 and EBS2 sites are indicated in grey. Tertiary interaction sites delta (δ) and delta prime (δ’) are labelled. Nucleotides are coloured according to their positions in the secondary structure.
