Figure S3. Structure-based alignment of GmCHS1 and CHS fromMedicago sativa (alfalfa).
(a) Superposition of GmCHS1/naringenin complex (cyan) and M. sativa CHS/naringenin complex (wheat, PDB ID: 1CGK), without indicating bound naringenin molecules. Important residues in both active sites are shown in stick models as will be shown in (b). (b) The super position of important residues and naringenin (NAR) molecules. Colors of the residues and naringenin molecules are corresponding to (a). The residues are labeled only for GmCHS1. (c) Surface representation of M. sativa CHS/malonyl-CoA complex (PDB ID: 1CML) with showing the bound malonyl-CoA in stick model, although its malonyl moiety is buried in the active site and thus not visible in this panel. Dotted circle indicates the position where the 1,4-piperazine di-ethane sulfonic acid molecule partially occupies in the coordinate. (d) Surface representation of GmCHS1/naringenin complex with showing the bound citrate ion in stick model.
