Figure 1. Occurrence of individual proteins in 17 Nocardiopsis proteomes ranged from one (a species-specific protein) to 17 (a core protein).

At the far left of the x-axis are species-specific proteins found in a single proteome (14,019 proteins; 14.1% of the total proteomes), while at the opposite end of the scale are Nocardiopsis core proteins found in all 17 proteomes (42,943; 43.1%).
