Comprehensive Temporal Protein Dynamics during Postirradiation Recovery in Deinococcus radiodurans

Figure 2

Principal component analysis (PCA) and cluster analysis of proteome data. (a) PCA score biplot of protein percentage data of samples during PIR. The cumulative data variance on the first two PCs was 52.3%. (b) Cluster analysis demonstrating the grouping of the replicate samples and 2 clusters with significantly enriched GO terms. (c) Expression levels are shown in the two clusters (Supplementary Table S8), in which cluster 1 includes translation (GOBP) and structural constituent of ribosome (GOMF) (119 proteins, ), and cluster 2 includes DNA damage and DNA repair (GOBP) (31 proteins, ). Proteins belonging to the cluster are shown in green to red based on the distance from the mean of all proteins in the cluster.
