Proteome overabundance enables respiration but limitation onsets carbon overflow

Rahul Kumar, Aleksandr Illarionov, Petri‐Jaan Lahtvee

The paper examines carbon overflow in yeast by linking proteome overabundance to respiration and energy efficiency, showing ribosome allocation determines growth rate and energy constraints trigger carbon overflow.
