| Research Abstract |
In this study, the comprehensive metaproteomic analysis using the liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was performed to investigate the dissolved (< 0.2 um) proteomic composition of viral lysates occurring during infection of a marine cyanobacterial Synechococcus sp. The analysis of the lysate proteome revealed that photosynthetic proteins, metabolic enzymes involved in amino acids and carbohydrates, and viral capsids were major components, possibly indicating the formation of dissolved proteins during viral infection was influenced by differences in the nature and subcellular localization of protein molecules.
