Multiple, non-allelic, intein-coding sequences in eukaryotic RNA polymerase genes

Table 1 Newly described inteins from the second largest subunit of RNA polymerases.

*No intein is present at the allelic site in another Emiliana huxleyi virus isolate, Emiliana huxleyi virus 86.
Intein size is expressed as amino-acid residue number. NCLDV indicates a member (or putative member) of the nucleocytoplasmic large DNA virus group.
