Figure 1.

A diagram illustrating the primary structure of the putative peroxygenase AsPXG1 from oat. The black box indicates 19 amino acids between residue 10 and 29 identical to the sequenced fragment of the peroxygenase protein purified from oat lipid particles previously. Two conserved His residues are located at position 76 and 144 that are involved in heme binding. The gray box indicates the EF-hand motif that is involved in calcium binding. The hatched box indicates a hydrophobic membrane-associated domain.
