Table 1 Turnover of sequence data

From: HitKeeper, a generic software package for hit list management

  db versions total entries sequences
current 39 ~ 7 · 106 ~ 5.7 · 106
total over 9 months 545 ~ 122 · 106 ~ 8.3 · 106
ratio 0.07 0.06 0.69
  1. 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).
