(A) Apo-SrtA NMR structure (PDB ID: 1IJA); (B) holo-SrtA NMR structure (PDB ID: 2KID); (C) apo-SrtA crystal structure (PDB ID: 1T2P) (D) holo-SrtA crystal structure; (E) superposition of all four SrtA structures, black ribbon: apo-SrtA NMR structure; red ribbon: holo-SrtA NMR structure; green ribbon: apo-SrtA crystal structure; blue ribbon: holo-SrtA crystal struture. (F) The binding site of SrtA is confined to the enclosing box used in the docking studies.
