Sequence homology with the P. aeruginosa structure (PDB code 2O4D) of the conserved α-helical hairpins responsible for putative peroxidase-related functional activity. Notes: 1. Chain fragments are pair compared with the range of 36-62 positions of AhpD from P. aeruginosa (PDB code 2O4D) as query. Identical residues are marked as bold ones. 2. Arrows in the upper line indicate the residues involved in reaction mechanism. 3. Residue positive (+) means similarity with approximately polar-polar and nonpolar-nonpolar pair of residues.
