Fig. 6.

Multiple sequence alignment presenting peroxidase-like genes coding for variants of plant ascorbate peroxidase-like proteins that most probably lack the heme group. Sequences are compared with functional ascorbate peroxidases from P. sativum (PsAPx) and yeast cytochrome c peroxidase (SceCcP) with known 3D structures. a Region of residues around distal histidine. b Region of residues around proximal histidine. Parameters for the alignment are described in the Sect. “Materials and methods”. Abbreviations of peroxidase names are taken from PeroxiBase
