Sequence comparison of HvPrx40 protein with selected peroxidases from cereal species. (A) Amino‐acid alignment of HvPrx40 with other peroxidases by Clustal W. Conserved residues are shaded in black. Arrow, putative cleavage site of N‐terminal signal peptide; dots, conserved cysteine residues forming four disulfide bridges; stars, conserved histidine residues of the catalytic centre. (B) Phylogenetic tree of HvPrx40 and selected peroxidases, based on Clustal W.
