ENZYME entry: EC 1.11.2.3

Accepted Name
plant seed peroxygenase
Alternative Name(s)
plant peroxygenase
soybean peroxygenase
Reaction catalysed
RH + ROOH <=> ROH + ROH
Comment(s)
  • A heme protein with calcium binding motif (caleosin-type).
  • Enzymes of this type include membrane-bound proteins found in seeds of different plants.
  • They catalyze the direct transfer of one oxygen atom from an organic hydroperoxide, which is reduced into its corresponding alcohol to a substrate which will be oxidized.
  • Reactions catalyzed include hydroxylation, epoxidation and sulfoxidation.
  • Preferred substrate and cosubstrate are unsaturated fatty acids and fatty acid hydroperoxides, respectively.
  • Plant seed peroxygenase is involved in the synthesis of cutin.
