Method Mass spectrometry and Western blot validation: "...researchers measured individual protein levels in average copies per cell under control conditions (growth for 96 h), along a 4-day time course, in response to heat shock, DNA damage and osmotic stress (Supplementary Table S2)."
Comments "For several well-characterized protein complexes, such as the GroEL/ES chaperonin (160 multimeric complexes per cell), DNA gyrase (50 A2B2 tetramers per cell) or ribonucleoside- diphosphate reductase (300 copies per cell), cellular abundances of the subunits reflect the expected complex stoichiometries closely (Figure 4B Supplementary Figure S13)."
