The ACP structure. (A) Ribbon diagram of the rat FAS ACP (2PNG), colored blue to red, corresponding to N to C termini.99,140 The post-translationally modified serine residue on helix 2 is shown. (B) The ACP surface electrostatic potential colored from red (negative) to blue (positive). (C) The crystal structure of the decanoyl thioester of E. coli ACP. The phosphopantetheine moiety is shown in red and the decanoyl moiety in green. Adapted from ref. 147.
