Figure 4: Aggregation of cyanobacterial abundant proteins (Phycobilosomes, phycobilisome linker proteins and allophycocyanins) to specific pH. Although some crossover of focussed abundant proteins observed in other pH range but by and large most of the abundant phycobiliprotiens are focussed in pH range of 5 to 7, thus allowing access to less abundant proteins which might have a positive effect on the dynamic range.
