Primary MS data and secondary data for: "Post-proline cleaving enzymes also show specificity to reduced cysteine"

raw LC-MS/MS data (Bruker Daltonics - timsTOF Pro and tims TOF SCP) and ESI-MS data (Bruker Daltonics - 15T ESI/MALDI FT-ICR MS) and related MASCOT generic files (.mgf) and search results (.csv) plus corresponding custom databases (*.fasta). Protein identifications were performed using MASCOT or PEAKS programs. Data were used to: extract cleavage preferences of Clarity Ferm AnPEP, ProAlanase or Neprosin. Target samples were: protein mixture (BSA, cytC, bCA2, myoglobin, 14-3-3) or human serum from a healthy donor or HEK cell lysate or human insulin or oxidized bovine insulin beta chain profile protein content of Clarity Ferm AnPEP and quantify the proteins Additional data are under Zenodo entry 10.5281/zenodo.13985598 Linked to the publication: Postproline Cleaving Enzymes also Show Specificity to Reduced Cysteine.
