Application
Microperoxidase (MP-11) has been used in a study to assess its electrochemistry by cyclic voltammetry with multi-walled carbon nanotubes (MWNTs). It has also been used in a study as a label to investigate electrochemical immunosensing.
Biochem/physiol Actions
The oxidation of methyl phenyl sulfide to methyl phenyl sulfoxide by Microperoxidase-11 was promoted by low concentrations of alcohol but inhibited by high levels in the solvent.
Preparation Note
Prepared by enzymatic degradation of equine heart cytochrome c.
Other Notes
The proposed structure is the heme portion of the cytochrome c molecule with amino acids 11-21 still attached.

Direct electron transfer reactions of microperoxidase were achieved with the help of semiconductive zinc oxide nanoparticles on a pyrolytic graphite electrode. The enzyme could also exhibit fine electrocatalytic activity towards the reduction of hydrogen peroxide. Thereby, a hydrogen peroxide biosensor
