Distribution of proteins.

<p>All proteins quantified at all specific growth rates has been divided into different groups by function. Proteins in the network covers enzymes that are involved in the reactions used for metabolic flux analysis and listed in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048223#pone.0048223.s001" target="_blank">File S1</a>, Table S1. Lists of all proteins can be seen in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048223#pone.0048223.s002" target="_blank">File S2</a>, Table S8.
