NDO-P has an active site cavity (A) that is 1 Å shallower than NDO-R (B). However, indole is still held in the same place next to the mononuclear iron (structure 2) similar to the indole in NDO-P (PDB id 1EG9). The π-π interaction between F307 in NDO-R and the nonhydroxylated ring of indole seemingly prevents indole from burying itself deeper into the cavity.
