Important residues around the heme pocket and redox-active residues in Il-DyP4. a Distal pocket for the conversion of H2O2 into H2O and proximal heme iron ligand (His312). b Conserved GXXDG motif. c, d Tryptophan and tyrosine residues potentially involved in substrate oxidation at the protein surface. The red sticks and green sticks, respectively, represent the tryptophan and tyrosine residues located at the surface of Il-DyP4, while the purple sticks represent the tyrosine residues located in the interior of Il-DyP4 and yellow sticks represent the heme cofactor
