Fig. 3. Mass spectrometry-based proteomic analysis of yeast^WT and yeast^ECP. (a) Proteome-wide analysis of yeast^WT and yeast^ECP after UV-C irradiation. The expression change was evaluated based on the fold change (Fc) value. The Fc value = spectral count of yeast^ECP/spectral count of yeast^WT; up-regulated with 1 < Fc and down-regulated with 1 > Fc. The known stress-related proteins are denoted in purple. (b) Proteome-wide analysis of yeast^ECP vs. yeast^WT before UV-C irradiation. Left bar graph: the number of changed proteins in each category of biological process. Right pie charts: sub-categorization of the cellular process or metabolic process.
