MtI structure has a mobile element (residues 323 to 227) that can adopt a <scene name='69/694235/Irp9_closed_state/2'>closed</scene> or <scene name='69/694235/2g5f_with_open_loop/1'>open conformation</scene> depending on whether or not ligands are bound to the active site. The closed conformation partially obstructs the active site. <ref>PMID:22607697</ref>. | MtI structure has a mobile element (residues 323 to 227) that can adopt a <scene name='69/694235/Irp9_closed_state/2'>closed</scene> or <scene name='69/694235/2g5f_with_open_loop/1'>open conformation</scene> depending on whether or not ligands are bound to the active site.

Inhibition studies have also shown a switch in binding mode at the MbtI active site for inhibitors carrying a substituted enolpyruvyl group compared to the chorismate substrate. Crystal structures and fluorescent-based thermal shift assays show that substituents larger than a methyl group are accommodated in the active site of MbtI through localized flexibility in the peptide backbone(Gamma Chi). | |||
