The phase diagram for baker's yeast. The area in shade is the 'dead zone'. Its boundaries, defined by Equations (13) and (15), are blurred to indicate they are crossover rather than sharp transitions. The colours indicate the average fraction of proteins tied up inside non-functional complexes in the yeast cytoplasm as defined in Equation (12). The white circle shows the C bar and m for a group of proteins coexpressed and colocalized in the yeast cytoplasm, whereas the white star and cross represents these parameters for the cell nucleus and mitochondria.
