Proteins with different identifiers but with the same sequence are counted only once.
The count of proteins for Swiss-Prot includes some proteins that were linked to experimental evidence but that were not linked to articles about the protein’s function (see Materials and Methods).
The count of proteins for EcoCyc does not include proteins that are not linked to any scientific articles (even though these are included in PaperBLAST’s database).
The total is less than the sum of the parts due to overlap of data sources.
