Actinorhodin acyl carrier protein (act ACP) from S. coelicolor was heterologously overexpressed in its apo form in E. coli BL21 (DE3) cells. These cells contained the plasmid pET11c C17S act ACP (courtesy of Dr. Tom Nicholson). This IPTG inducible vector is both easier to use and more reliable than the heat inducible pT7-7 version originally constructed.

Ensemble of 20 structures of butyrylated act ACP. Malonyl ACP was synthesized using Malonyl CoA (12C,14N) and holosynthase to load the acylated 4'phosphopantetheine chain onto the ACP.

All experiments were collected on a single sample over a 2 week period.
