Comparison of structures of the Rpl8 peptide bound to NO66. (a) Chowdhury et al. (2014BB6) used a cross-linking strategy to determine the complex structures of NO66 and Rpl8 peptides. In contrast, we determined the structure of NO66176–C in complex with Rpl8204–224 in the native state. Cross-linking by disulfide bonds affects the conformation of the Rpl8 peptide bound to NO66. The Rpl8 peptide binds to NO66 in the native state and is coloured yellow. Rpl8 peptides cross-linked to NO66 are coloured green (complex 1; PDB entry 4ccm ), blue (complex 2; PDB entry 4ccn ) and magenta (complex 3; PDB entry 4cco ), respectively. Sequence-alignment results of Rpl8 peptides from these complex structures are shown at the bottom of the panel. Amino-acid residues mutated to cysteine are highlighted in red. (b, c, d) Detailed comparison of the Rpl8 conformation between the native state and three cross-linked structures.
