(A) Relative functional composition for each methodology. Values represent the proportion of proteins with identical functional name on total identified protein using TAX-DB, NAM-DB, AM-DB, or Comb-DB in both gel-free and gel-based approaches. The number of peptides detected for each protein was used as quantitative value. Protein isoforms and/or sub-units were grouped under the same function. Functions displaying a proportion <1% were gathered into “Other” category. (B) Venn diagrams showing the number of common and unique protein functions.
