Comments "Rubisco is the predominant protein in leaves of C3 plants and may contribute up to 50% to the soluble leaf proteins (1st primary source) and 20–30% of total leaf nitrogen (BNID 101769). In leaves of C4 plants, Rubisco still contributes ~30% to the soluble proteins (2nd primary source) and 5–9% of total leaf nitrogen (BNID 101770)."
