Fig. 6

Structural comparisons of the two adjacent RbcS subunits (RbcS1 and RbcS2) between Tch. tepidum form-IAq RuBisCO and other representative form-I RuBisCOs. The six-residue insert in the N-terminal domain is shown in red. All other structures are superimposed with that of Tch. tepidum (gray). Form-IAc: H. neapolitanus (cyan, PDB: 7SMK), form-IB: Spinacia oleracea (green, PDB: 1RXO), form-IBc: Synechococcus elongatus PCC6301 (pink, PDB: 1RSC), form-IC: Cereibacter sphaeroides (orange, PDB: 5NV3), form-ID: Griffithsia monilis (slate blue, PDB: 8BDB). βE and βF indicate two additional β-strands in the form-IC and ID RbcS subunits. The extended βA-βB loop in the Spinacia oleracea RbcS subunit is indicated by an arrow.
