There are two distinct forms of rubisco. Form I is found in vascular plants, algae, and cyanobacteria; form II is confined to certain photosynthetic bacteria, Some statements about the Rubisco is given;

a.) A complex form I structure with eight identical large subunits each containing a catalytic site, and eight identical small subunits of uncertain function

b.) The form II rubisco of photosynthetic bacteria is simpler in structure, having two subunits that in many respects resemble the large subunits of the plant enzyme

c.) The plant enzyme has an exceptionally low turnover number; only three molecules of CO2 are fixed per second per molecule of rubisco at 25 o C

d.) Rubisco makes up almost 50% of soluble protein in chloroplasts and is probably one of the most abundant enzymes in the biosphere
