Figure 3
An acidic pocket conserved in the DUF1089 family suggests a ligand-binding site. The PA1994 monomers, colored white and blue, are shown as a ribbon diagram and as a surface representation. Invariant residues (Asp101, Asp103 and Tyr147) are indicated, with the conserved Asn111 located behind the pocket labeled in parentheses. The ethylene glycol (EDO) and MPD molecules that line the entrance to the acidic pocket in the crystal are shown in green.
