(a–b) Ribbon diagrams of the trimeric structures of SIB1–CutA1 with secondary structure elements. In the trimeric structure each monomer is coloured differently. (b) Stereo drawing. (c–d) Superimposed structures of SIB1–CutA1 (green) with Ec-CutA1 (orange) and Ph-CutA1 (purple). (e–f) Ribbon diagrams of the monomeric structure of SIB1–CutA1 with secondary structure elements. (e) Residues described in the text are shown. (f) Stereo drawing. (g–i) Close-up views of β2 (β2a and β2b) and β3. Residues described in the text are shown. (g) SIB1–CutA1. (h) Ec-Cut-A1. (i) Ph-CutA1. |
