Overall structure of PA4991. (a) The surface of the FAD-binding domain is shown in light blue and that of the substrate-binding domain in light yellow. Secondary-structure elements are labelled and shown as a cartoon model with red α-helices and yellow β-strands. Disordered regions are displayed as dotted lines. The FAD molecule is shown in a stick representation. (b) Electrostatic potential surface of PA4991. The FAD-binding pocket and entrance to the active site is highlighted with a yellow arrow. The bound FAD molecule is shown as a stick model. |
