A multi-omic analysis of an Enterococcus faecium mutant reveals genetic mutation and dramatic changes of mRNA and protein expressions


ABSTRACT: Three iTRAQ8plex experiment replicate using TripleToF 5600 system. Protein identification were performed using the ProteinPilot software (version 4.0.8085,Paragon Algorithm version 4.0.0.0).All MS/MS spectra was search against amino acids sequences which is annotated from genome. The search parameters was set as follows: Cys. Alkylation: Iodoacetic acid, Digestion: Trypsin, ID Focus: Biological modifications, Search Effort: Thorough. The search results was filter using Local FDR 5%.

INSTRUMENT(S): TripleTOF 5600

ORGANISM(S): Enterococcus Faecalis (streptococcus Faecalis)

<h4>Background</h4>For a long time, Enterococcus faecium was considered a harmless commensal of the mammalian gastrointestinal (GI) tract and was used as a probiotic in fermented foods. In recent decades, E. faecium has been recognised as an opportunistic pathogen that causes diseases such as neonatal meningitis, urinary tract infections, bacteremia, bacterial endocarditis and diverticulitis. E. faecium could be taken into space with astronauts and exposed to the space environment. Thus, it is n  ...[more]
