Figure 6
A small number of discrete amino-acid replacements give M. truncatula GSII-2b significant resistance to herbicide inhibition. The amino-acid sequence positions unique to M. truncatula GSII-2b and located in the vicinity of the MSO binding site are highlighted (stick representation) in the experimental model of M. truncatula GSII-1a. The active site at the interface between subunits A and B (colour code as in Fig. 2[link]) is depicted and a methionine-S-sulfoximine molecule is shown in space-filling representation, as found in the complex with Z. mays GSII-1a (PDB entry 2d3b; Unno et al., 2006BB52).
