Extended Data Fig. 4: The binding site, domain organization and secondary structures of TEF30.

a, Superposition of the TEF30-C (gray), TEF302-C2-I (sky blue), TEF302-C2-II (pink) and TEF30-C2S (light green) structures on the TEF30-C regions. The other parts of TEF302-C2-I, TEF302-C2-II and TEF30-C2S are omitted for clarity. The cartoon models except that of TEF30 are shown in the transparent mode. b, The cartoon model of TEF30 illustrating its secondary structures. The β-sheets and α-helices are indicated by the arrows and cylinders. c, The TEF30-C structure showing the position of TEF30 in the complex. Left: Stromal view; right: side view. TEF30 is shown as the cartoon and transparent surface models, PSII-C is presented as surface model.
