aListed are the results with p ≤ 0.05 by Student’s t-test (two-tailed, paired). Statistical analysis results can be found in S1-5Tables; b -, no significant change; cThe 11 putative FtsH substrate proteins were bold-faced; dThe four proteins whose degradation by FtsH was demonstrated in vitro (Fig. 4C) were underlined.
