Protein allocation and utilization in the versatile chemolithoautotroph .

Bacteria must balance the different needs for substrate assimilation, growth functions, and resilience in order to thrive in their environment. Of all cellular macromolecules, the bacterial proteome is by far the most important resource and its size is limited. Here, we investigated how the highly versatile 'knallgas' bacterium reallocates protein resources when grown on different limiting substrates and with different growth rates.
