  • a All 23 genes with significant differences (sixfold change and differential expression supported by a P value of less than or equal to 0.05) in mRNA or protein expression between control exponential-phase growth (n = 4) and any other condition are listed.

  • b %S, percentage of sulfur-containing amino acids.

  • c Values indicate the fold change in expression relative to the expression during control exponential-phase growth. Values are only displayed if the difference in expression is supported by a P value of ≤0.05 and are in boldface when the significance level is ≤0.05 after correcting for multiple comparisons. LE, sulfur-limited exponential phase; LS, sulfur-limited stationary phase; CS, control stationary phase; ND, not detected by mass spectrometry at any time point, potentially due to methodological limitations on extracting insoluble proteins, such as those localized to the membrane.

  • d Downstream from a SAM-V riboswitch.
