EC Tree
1.11.1.16 versatile peroxidaseIUBMB Comments
A hemoprotein. This ligninolytic peroxidase combines the substrate-specificity characteristics of the two other ligninolytic peroxidases, EC 1.11.1.13, manganese peroxidase and EC 1.11.1.14, lignin peroxidase. Unlike these two enzymes, it is also able to oxidize phenols, hydroquinones and both low- and high-redox-potential dyes, due to a hybrid molecular architecture that involves multiple binding sites for substrates [2,4].

manganese peroxidase activity is more efficient than lignin peroxidase activity, with activity increasing with increasing concentrations of Mn2+ due to a second metal binding site involved in homotropic substrate Mn2+ activation. The activation of maganese peroxidase is also accompanied by a decrease in both activation energy and substrate Mn2+ affinity

physiological function
despite the presence of Mn2+ in the medium, a transformant overexpressing the enzyme produces mnp4 transcripts as well as versatile peroxidase activity as early as 4 days after inoculation. The level of expression is constant throughout 10 days of incubation and the activity is comparable to the typical activity in Mn2+-deficient media
