Principal components analysis (PCA) of antioxidative properties in all metal-binding proteins as well as all periplasmic proteins. Antioxidative properties are computed for all metal-binding proteins and averaged for every strain. A feature matrix containing these properties is used as input to PCA, and subsequently, strains with predicted ROStypes (top left) and strains with pathotype annotations (bottom left) are highlighted. PCA for all proteins localized to the periplasm is also shown (right). These two general groups of proteins show clusters with the highest homogeneity in regards to predicted endogenous ROS or pathotype labels
