Global proteome survey of protocatechuate- and glucose-grown Corynebacterium glutamicum reveals multiple physiological differences

► Global quantitative proteome study with comprehensive membrane proteome coverage. ► Aromatic compounds as carbon sources have substantial impact on bacterial physiology, going much beyond catabolic pathways. ► Several obvious differences in the proteome of protocatechuate-grown to previously analysed benzoate-grown C. glutamicum were discovered. ► Indications for global and local regulation mechanisms were found.
