Full 2022-06 Build Summary
115ProteomeXchange datasets
596,839distinct peptides
18,267canonical core proteins


The Arabidopsis PeptideAtlas provides a compendium of results from uniformly reprocessed mass spectrometry proteomics datasets.

Publicly-available Arabidopsis thaliana columbia-0 datasets were downloaded from ProteomeXchange and reprocessed from the raw files using the Trans-Proteomic Pipeline suite of tools. A publication describing the build is available.

Column descriptions ▲
Entries: Number of entries in each chromosome
Canonical: Proteins seen with 2 distinct, uniquely mapping peptides
Uncertain: Proteins with some evidence that is not sufficient for canonical status
Redundant: Proteins that have peptides that map to them, but not uniquely and thus not needed to explain the observed peptides
Not Observed: No detections at all in PeptideAtlas above our very stringent threshold



Below are individual Arabidopsis thaliana PeptideAtlas builds available for download in various flat file formats. Note that not all files contain all information from the build. A build subtitled "PSM FDR=0.002" denotes a PSM FDR threshold of 0.002 (0.2%) is applied to every sample in the build.

Filename Size # Sequences Description
revised_mito_plastid_edited.fasta 48KB 114 Protein ids and sequences after application of editing for the 79 plastid-encoded and 35 mitochondrial-encoded proteins and pseudogenes; minor frequency edits are not applied but all high frequency edits are included
revised_mito_plastid_edited.peff 52KB 114 Protein ids and their amino acid sequences with all possible variants supplied in PEFF format. PEFF allows for encoding the variants in a compact way in the file. Comet and some other search engines support PEFF.
revised_mito_plastid_pre-edit.fasta 48KB 114 Protein ids and unedited sequences (with the exception of essential edits for start and stop codons that need to be applied to generate a protein) for the 79 plastid-encoded and 35 mitochondrial-encoded proteins and pseudogenes
revised_mito_plastid_all-editing-permutations.fasta 1.2MB 3,818 Proteins ids and the >10.000 sequence variants (see Materials and Methods) to allow for complete and exhaustive MSMS data base search of all possible edits and allow for partial editing (similar as we did in this study)
