The crystal structure shows the heme bound inside the hydrophobic pore of the protein, where it appears inaccessible for substrates. Yet, good catalytic activity and moderate enantioselectivity was observed in the abiological cyclopropanation reaction. We proposed that the dynamic nature of the structure of the LmrR protein is key to the observed activity. This was supported by molecular dynamics simulations, which showed transient formation of opened conformations allowing for binding of substrates and formation of pre-catalytic structures.
