Enzyme number :EC 1.11.1.13

H2O2 에 의존 하여 Mn2+ 를 Mn3+ 로 산화 시키고 , Mn3+ 가 유기 물질을 산화 시키게 된다 . iron protoporphyrin IX group 을 가지고 있는 glycoprotein 이다 .

MnP는 다양한 phenol 과 dye 를 산화 시킬수 있다 .

  • Catalytic cycle of manganese peroxidase

Manganese peroxidase.GIF


  • fungal taxa : Basidiomycota
  • Localization : Extracellular


• H2O2-dependent one-electron oxidation of Mn2+ to Mn3+, which subsequently oxidizes organic compounds • Redox potential of 1.0–1.2 V • Mn3+-mediated oxidation of various phenols and aromatic amines • Extended substrate range in the presence of co-oxidants (organic SH-containing compounds, unsaturated fatty acids and their derivatives) • Activity in the acidic pH range 60,68,70
