a

Proteins with different identifiers but with the same sequence are counted only once.

b

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).

c

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).

d

The total is less than the sum of the parts due to overlap of data sources.
