Subject area	Biology,Chemistry
More specific subject area	Microbial Proteomics, Bacterial physiology
Type of data	LC-ESI-MS/MS data
How data was acquired	Mass spectrometry
Data format	MS/MS data obtained from Orbitrap velos (Thermo scientific) was used for the identification of proteins.
Experimental factors	The protein of OMVs isolated form an Antarctic bacterium was identified using SEQUEST, MASCOT and PEAKS programs. The proteins commonly identified in all the three programs were accepted for further functional analysis.
Experimental features	In gel digested proteins with Trypsin were extracted with 5% TFA in 50% acetonitrile. Dried and desalted the peptides with Zip-tip C18 columns and loaded on Nano LC-ESI MS/MS.
Data source location	CSIR-Centre for Cellular and Molecular Biology, Hyderabad, India.
Data accessibility	Achieves of PRIDE, PXD 000221. The identified proteins were published in Journal of Proteome research [1].
