SRM measurements of a subset of <i>C. jejuni</i> metabolic enzymes.

1For each peptide, three SRM transitions were measured. 2Intensity values were represented by integrated peak area obtained from extracted ion chromatograms. 3Fold change of fragment ion intensities between the 2 h and 20 h samples; negative values denote decreased levels in the 20 h samples. 4Spectral counts obtained for the same biological replicate. 5Fold change of peptide spectral counts between the 2 h and 20 h samples; negative values denote decreased levels in the 20 h samples. 6Peak not detected due to low peptide ion signals. 7Fold change not determined. In this case, a large negative fold value would be expected.
