Figure 4

(A) Structural superposition of ATP-bound MsFadD32 and adenylate analog- and phosphopantetheine-bound PA1221 protein. The N- and C-terminal domains of MsFadD32 are colored green and wheat, respectively. The N- and C-terminal subdomains and the peptidyl carrier protein domain of PA1221 are colored pale cyan, white and pink, respectively. The covalently-connected adenylate analog and phosphopantetheine are shown as magenta sticks. Phe284 of MsFadD32 is shown as a red stick. (B) Surface representation of the two domains of MsFadD32 showing the phosphopantetheine-binding tunnel.
