Proteomic responses of Roseobacter litoralis OCh149 to starvation and light regimen.

ABSTRACT: Roseobacter litoralis OCh149 is a type strain of aerobic anoxygenic phototrophic bacteria in marine Roseobacter clade. Its full genome has been sequenced; however, proteomic research, which will give deeper insights into the environmental stimuli on gene expression networks, has yet to be performed. In the present study, a proteomic approach was employed to analyze the status of R. litoralis OCh149 in carbon starvation during the stationary phase and its responses to a dark/light regimen (12 h:12 h) in both exponential and stationary phases. LC-MS/MS-based analysis of highly abundant proteins under carbon starvation revealed that proteins involved in transport, the transcription/translation process and carbohydrate metabolism were the major functional categories, while poly-β-hydroxyalkano
