CHX treatment affects the abundance of 33 PM proteins.

Fold-change ratios of the abundance of PM proteins identified in the proteomic screening after CHX treatment. The first two columns indicate the UniProtKB accession numbers and names of proteins. The third column corresponds to the WT+CHX/WT ctrl ratio, specifying the protein relative abundance in the CHX-treated WT divided by its relative abundance in the mock-treated WT. The same total amount of proteins was analyzed in both conditions. The blue and red colors specify whether the ratio is significantly lower or higher than one after hypothesis testing (i.e., with a p-value < 0.05), respectively. A protein with a blue ratio (WT+CHX/WT ctrl < 1) is less abundant in the WT+CHX than in the WT ctrl, indicating a decrease in abundance upon CHX treatment. Inversely, a protein displaying a red ratio (WT+CHX/WT ctrl > 1) is more abundant in the WT+CHX than in the WT ctrl, suggesting an increase of the protein abundance upon CHX treatment. Proteins are classified according to their fold change after CHX treatment of WT strain, from the greatest decrease (Ptr2) to the greatest increase in abundance (Zeo1). Displayed ratios correspond to the geometric means from 6 independent experiments.
