Functional quantitative proteomic overview of cells growing in defined and rich medium. Summary of proteome data of E. coli BL21 grown at exponential (A) and stationary phases (B, abundances at exponential phase are indicated in B also by solid lines for comparison) in defined (gray bars) and rich (open bars) media. Numbers in brackets after each functional category are the number of proteins that were identified within this category. An average of protein abundances from cells grown in LB and TB media was calculated to represent the proteome of cells grown in rich medium. The entire data sets are given in Additional file 1: Table S1.
