Fig. 1: Overall structures and active sites of VdPDA1 and Pst_13661.
From: Inhibition of chitin deacetylases to attenuate plant fungal diseases
a, b Cartoon representation of the overall structures of VdPDA1 (a) and Pst_13661 (b), and surface representation of their substrate-binding pockets (gray). The zinc ion is shown as a sphere in the slate. c Alignment of the overall structures of the two enzymes and surface representation of their active sites. VdPDA1 is shown in orange and Pst_13661 is shown in blue. The metal-binding triad (Asp56/Asp59-His108/His111-His112/His115), catalytic residues (general base Asp55/Asp58 and general acid His201/His207), a Zn2+ ion (slate sphere), and a water molecule (red sphere) are shown. The amino acids are labeled by their one-letter abbreviations.
