Numbers of protein database versions, entries and sequences in HitKeeper behind the MyHits website, counted at the end of a nine-months period and cumulated over the same time. The ratios indicate frequent updates of the database source files (545 individual releases for a final count of 39 database versions), frequent modifications of the annotations for the complete entries, but a much lower rate of sequence changes (69% remain unchanged over time).
