Extended Data Fig. 2: Structural comparison of AetD with haem oxygenase and other HDO enzymes.
From: A single diiron enzyme catalyses the oxidative rearrangement of tryptophan to indole nitrile

All HDO enzymes share the common architecture of three core helices containing metal-binding ligands, and four auxiliary helices. a, Haem oxygenase (PDB ID: 1WOW) b, AetD structure presented in this work. c, CADD (PDB ID: 1RCW). d, UndA (PDB ID: 6P5Q). e, BesC (PDB ID: 7TWA). f, SznF (PDB ID: 6VZY).
