Structural classification of ICDH based on AceK binding. (A) AceK-Ec-ICDH complex structure. The SRL (green) of AceK (teal) extends into the Ec-ICDH (purple) structure. The main binding elements, ARS and P-loop (blue), for AceK on ICDH are shown. (B) Classification of ICDH based on the structural elements in the corresponding P-loop and ARS regions. For clarity only one representative structure is shown for each class (Class A: Bp-ICDH, Class B: Pc-ICDH, Class C: Bs-ICDH and Class D: Ap-ICDH).
