Frequency of P7 structure variants in fungal mt Group ID introns. The numbers are compiled from the search result with the updated ID ERPIN model (see main text), identifying a total of 1,107 hits (span of E-values from 7.17e-44 to 4.94e-11); none of the respective intron sequences was identified with other group-specific searches, and all are therefore considered bona fide ID introns. Variant motifs with at least five identical P7 matches (numbers indicated below the structures) are listed, and nucleotides that differ from the most prevalent motif are marked in red. The most prevalent P7 motif (879 hits) is 5’-C_A_GACUG…CAGUCG-3′. The blue asterisk beside motifs indicates listing of the same motif in the Michel and Westhof compilation (Michel and Westhof, 1990).
