From: Characterization of oligopeptide patterns in large protein sets
Kingdom distributions of protein number and sequence length. The pie charts show the total sequence length and the number of proteins found in the kingdoms of archaea (A), bacteria (B) and eukaryotes (E). The fraction of proteins in bacteria and eukaryotes are approximately the same, but the eukaryotic proteins are 8% longer on average in the genome set compared to Swiss-Prot. The archaeal portion constitutes only 2–5% of the data and will in absolute number of observations therefore be considerably lower.
