Fig. 5

Functional plasticity residues and regions in the C-terminal domain of plant MTPSs. The two metal-binding motifs (DDXXD and NSE/DTE motifs) and the four plasticity regions (Regions 1–4) are framed in the same colors as Fig. 3. Residues affecting substrate selectivity and product specificity are, respectively, highlighted in orange and green background, while residues affecting both substrate and product properties are highlighted in yellow background.
