Table 1 Size of proteomic, simulated proteogenomic, and real proteogenomic databases for yeast

From: Evaluating the effect of database inflation in proteogenomic search on sensitive and reliable peptide identification

Database (target + decoy) # Target (AA) # Decoy (AA)
Proteomic 1Ty + 1Dy 3,062,279 3,062,279
Simulated proteogenomic 1T1Dy + 2Dy 6,124,558 6,124,558
1T2Dy + 3Dy 9,186,837 9,186,837
1T5Dy + 6Dy 18,373,674 18,373,674
Real proteogenomic 6FTTy + 6FTDy 9,654,965 9,654,965
  1. Database sizes are measured by total length (AA) of contained peptides. 1Ty: yeast reference protein database. nDy: decoy database of which size is n times of 1Ty. 6FTTy: proteogenomic database constructed by 6-frame translation of yeast genome. 6FTDy: decoy database for 6FTTy
