In table 2, on p.17, the number of Pfams present in the top row of the 10th column is 713 (not 816). The accidental transposition of “816” (from the 5th column to the 10th column), does not alter any results, figures, calculations, or conclusions that are reported in this article. The primary data used for this study, including that in table 2, may be freely downloaded from the Pfam website (Pfam release 27, July 2–3, 2014).
