Coronavirus-derived sequences with the peptides identified by proteomics analysis and protein coverage. Proteins were analyzed by reverse phase (RP)-liquid chromatography (LC)-mass spectrometry (MS)/MS (RP-LC-MS/MS) using an Easy-nLC II system coupled to an ion trap LCQ Fleet mass spectrometer (Thermo Fisher Scientific) as previously reported [3]. For this study, MS/MS raw files were searched again against a compiled database containing all proteins from Felidae, coronavirus, Drosophila and Ctenocephalidae (78265, 30637, 342897 and 475 Uniprot entries in May 2020, respectively). Amino acid sequences of proteins corresponding to the Uniprot (https://www.uniprot.org) entries shown in parenthesis. The sequences of the peptides identified by proteomics analysis are highlighted in green and the sum of their amino acids reflect protein coverage when compared to the sequence of the identified proteins
