LC-MS/MS analysis using a TripleTOF 5600 (ABSCIEX) was performed on samples collected during exponential phase (OD600 = 0.4), stationary phase (OD600 = 4.0), at the initiation of sporulation (t0), and 3h after the induction of sporulation (t3). Adjusted spectral counts were calculated by counting the number of peptides with at least 95% confidence that were identified divided by the total amino acid length of the protein.

^aTotal spectral counts for all proteins sum to 1; spectral counts for proteins were multiplied by 10⁴.

^bND: not detected.

^cSporulation-specific proteins.
