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.

Other Notes

The proposed structure is the heme portion of the cytochrome c molecule with amino acids 11-21 still attached.

Preparation Note

Prepared by enzymatic degradation of equine heart cytochrome c.

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
