Figure 5.  Important structural features of BC. All images rendered using PyMOL. (A) Yeast ACC BC shown in cartoons. The A domain is shown in orange, B in green, C in blue, and the AB linker in magenta. Accession code 1W93 (Shen et al., 2004). (B) The binding site of soraphen A from yeast BC. The active site is shown in surface mode and the ligand in a stick model. Assession code 1W96 (Shen et al., 2004). (C) The binding site of ATP from E. coli BC mutant E288K. Similarlarly, The active site is shown in surface mode and the substrate in a stick model. The surface is rendered slightly transparent so that binding can be fully visualized. Accession code 1DV2 (Thoden et al., 1999).
