Comparison of the FA binding site in S. aureus complexes with previously available structures. Structures were aligned based on EF-G and side chains within 4.5 Å of FA are shown as sticks. (A) Overlay of the FA binding site in the S. aureus CHI state and EcCHI (PDB ID: 7N2C). (B) Overlay of the FA binding site in the S. aureus CHI state and TtPOST (PDB ID: 4WQF).
