Get the Protein-Accession - GO-ids mapping for every Protein in e.coli K12

I only found the annotation file for e.coli from EcoCyc: "gene_association.ecocyc" But I can´t open the file. I just need a simple text file, that maps ProteinAccession to all GO-ids.

SOLVED: I just renamed the file to .gaf since it already is in the .gaf format.

protein go gene ontology

Glad you managed to get your data. Alternatively, you could also query UniProtKB, e.g.

http://www.uniprot.org/uniprot/?query=organism:83333 http://www.uniprot.org/uniprot/?query=proteome:UP000000625

and then customize your output to include a column for GO identifers, optionally remove all other columns, and download the file in tab-separated format (http://www.uniprot.org/help/customize)

This results in (preview of first 10 entries in the list): http://www.uniprot.org/uniprot/?sort=score&desc=&compress=no&query=organism:%22Escherichia%20coli%20%28strain%20K12%29%20[83333]%22&fil=&limit=10&force=no&preview=true&format=tab&columns=id,go-id
