I am currently trying to search through proteomes to see if specific proteins are present. I am, however, a little confused by what is available in the EMBL-EBI PRIDE database. There appears to be much more information than I need at the moment.

Is there a way to condense the available information for PRIDE entries down to a fasta file, or something similar, of the protein sequences found in the proteome?

EDIT: I should mention that I am trying to search for my protein of interest by sequence as it would be from an organism different from the one that the PRIDE data was collected in (ie: its food).
