Proteomic Insight into functional changes of proteorhodopsin-containing bacterial species Psychroflexus torquis under different illumination and salinity levels.

Data from ProteomeXchange, PXD ID: PXD000673. File: 70Lb1.mzXML. Published as part of J Proteome Res. 2015 Jul 16 . From the Abstract: {{i}} The extremely psychrophilic proteorhodopsin-containing bacterial species Psychroflexus torquis is considered a model sea-ice microorganism, which has adapted to an epiphytic lifestyle. So far not much is known about proteorhodopsin-based phototrophy and associated life strategies of sea ice bacteria although it has been previously shown that P. torquis can gain growth advantage from light using a proteorhodopsin proton pump the activity of which is influenced by environmental salinity. The comprehensive quantitative proteomic study performed here indicated that P. torquis responds to changing salinity and illumination conditions ... {{/i}}
