Proteomic dataset: Profiling of cultivated Echerichia coli isolates from Crohn's disease patients and healthy individuals

One of the dysbioses often observed in Crohn's disease (CD) patients is an increased abundance of Escherichia coli (10–100 fold compared to healthy individuals) (Gevers et al., 2014). The data reported is a large-scale proteome profile for E. coli isolates collected from CD patients and healthy individuals. 43 isolates were achieved from 30 CD patients (17 male, 12 female, median age 30) and 19 isolates from 7 healthy individuals (7 male, median age 19). Isolates were cultivated on LB medium at aerobic conditions up to medium log phase. Protein extraction was performed with sodium deoxycholate (DCNa) and urea, alcylation with tris(2-carboxyethyl)phosphine and iodacetamide. Protein trypsinolysis was performed as described in (Matyushkina et al., 2016). Total cell proteomes were analysed by shotgun proteomics with HPLC-MS/MS on a maXis qTOF mass-spectrometer. The data including HPLC-MS/MS raw files and exported Mascot search results was deposited to the PRIDE repository project accession: PXD010920, project https://doi.org/10.6019/PXD010920.
