Mean protein lengths for organisms whose genomes were sequenced

Range 270±9 for 5 archeae: 330±5 for 15 bacteria: 449±25 for 2 eukaryotes Amino acids/protein
Organism Various
Reference Zhang J. Protein-length distributions for the three domains of life. Trends Genet. 2000 Mar16(3):107-9. p.107 left column 2nd paragraphPubMed ID10689349
Method The annotated genome sequences were downloaded from GenBank for all species except Thermotoga maritima, Saccharomyces cerevisiae and Caenorhabditis elegans, which were downloaded from link link and link respectively.
Comments The mean protein lengths (MPLs) for the five archaeal species are between 237 and 282 amino acids, with an average of 270±9. This number becomes 330±5 for 15 bacteria and 449±25 for two eukaryotes (see keywords section for names of organisms).
