The structure of the N-terminal domain of Rubisco is highly conserved among different photosynthetic organisms. A computerized alignment of the three-dimensional structures of Rubisco from different organisms was performed using the published structures for spinach (1AUS, blue), tobacco (1EJ7, red), G. partita (a rhodophyte, 1BWV, orange), T. kodakaraensis (a photosynthetic archeaon, 1GEH, yellow), R. rubrum (a purple bacterium, 5RUB, cyan), and from Synechococcus PCC6301 (a cyanobacterium, 1RBL, purple). All structures were compared using SPDB Viewer, with the structure of C. reinhardtii (a green alga, 1GK8, green). The RMS deviation values of each alignment appear below each superimposed structure.
