Summary of results from analysis of the proteome. The majority of spots that are different in the ΔbldA mutant are most abundant in M600 during the stationary phase. (A) Grouping of identified protein spots according to their abundance profiles in M600. (B) Protein spots identified that are considered to be altered in expression in ΔbldA. Figures given are the number of spots that reproducibly exhibit a two-fold or higher change in abundance in the ΔbldA mutant strain, followed by a bracketed figure indicating the number of these that are also statistically significantly different. (C) Table showing that the statistical approach is limited to proteins that are reproducibly more abundant in at least three of the five timepoints.
