Proposed model for 5′-GTP binding (C, orange; N, blue; O, red; P, purple) to the Fe4 ion of cluster II (S, yellow; Fe, green). The 5′-GTP model derived by X-ray crystallography (PDB entry 2FB3) is shown in white. Reprinted with permission from Lees, N., et al.. [188] Copyright 2009 American Chemical Society.
