Crystal structures of crosslinked complexes. (A) Comparison of the FabA=AcpP (PDB: 4KEH) and FabB=AcpP (PDB:5KOH) complexes. Both homodimers have two ACPs attached at the entrance to each active site, located at the interface of the monomers. However, the FabA=AcpP complex shows two different binding events, and are distinguished by numbering. (B) Comparison of the protein-ACP interfaces.
