Figure S4. Part A. 3D homology models reconstructed for MutY of the C. phaseoliformis symbiont. The model was reconstructed using the Swiss-Model Workspace (http://swissmodel.expasy.org/ webcite) based on the crystal structure of Geobacillus stearothermophilus MutY  (PDB accession # = 3FSP) as a template. A, Alignment of MutY amino acid sequences of Calyptogena symbionts and G. stearothermophilus. Sequences were aligned using ClustalW. a, MutY sequence from Phe-8 to Ser-360 in G. stearothermophilus. b, Secondary structure of G. stearothermophilus MutY (3FSP). Red rectangles, α-helices; blue arrows, β-strands. c, MutY sequence from Val-1 to Asp-341 in the symbiont of C. phaseoliformis. d, MutY sequence of N-terminal ORF in Ruthia magnifica. e, MutY sequence of C-terminal ORF in R. magnifica.
