Fig. 4. Model of the A-state TycC3-PCP/Sfp complex. The Sfp protein is shown in yellow, TycC3-PCP in blue, and CoA in red. The arrow indicates the position of the reactive thiol group of CoA. (A) Proposed position of CoA in Sfp based on the electron density of the adenyl phosphorus in the Sfp crystal structure (11) and calculations with the program auto-Dock 3 (27). (B) Space-filling model of the Sfp/A-state TycC3-PCP complex.
