FIG. 11.

Ribbon diagram of the minimized average structure of apo-Dcp (PDP entry 1HQB). Residues shown in white bury the Trp⁶⁷ side chain (purple) in the hydrophobic core. Other key residues include the conserved Glu³³ and Asp³⁸(red) and Ser³⁹ (yellow), as well as a cluster of basic residues (blue) proximal to the phosphopantetheine attachment site (Arg⁶⁴, Lys⁶⁵, and Lys⁷²).
