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.
