Amino acid sequences of the large (A) and small (B) subunits of tobacco (Mazur and Chui, 1985; Shinozaki et al., 1986) and sunflower (B. Ranty and S. Gutteridge, unpublished data, accession no. AF097517; Waksman and Freyssinet, 1987) Rubisco showing the positions where there are amino acid differences. A significant feature of the sunflower large subunit is the C terminus extended by eight residues. (Accession numbers for the tobacco large and small subunits are P00876 and P26666, respectively. Those for the sunflower large and small subunits are P45738 and P08705, respectively.)
