Figure 6: Distribution of substitutions mapped onto crystal structures of RuBisCO.
From: Biochemical characterization of predicted Precambrian RuBisCO
(a) Complex of one large (red) and one small (blue) subunit from the crystal structure of Form 1B RuBisCO of Synechococcus elongatus PCC6301 (PDB ID: 1RBC). Substitutions between the crystal structure and the β-MRCA RuBisCO are highlighted in yellow. (b) Complex of one large (red) and one small (blue) subunit from the crystal structure of Form 1A RuBisCO of Halothiobacillus neapolitanus (PDB ID: 1SVD). Substitutions between the crystal structure and the α-MRCA RuBisCO are highlighted in yellow. The two models are similarly oriented.
