Peroxidase is a fungal enzyme which has a key role in the ligninolytic cycle, the process by which the structural component of plant walls, lignin, is degraded. Lignin Peroxidase has the activity of unit corresponding to the amount of enzyme, which oxidizes 1 μmole 3.4-dimethoxybenzyl alcohol per minute at pH 3.0 and 30 °C.

Function:
Peroxidase be usde for biochemical research, enzyme labeling is a major enzyme used in medicine for the determination of biological fluids in the glucose and galactose levels, as a diagnostic enzyme.
It can be used in biochemical diagnostic kits such as blood glucose, triglyceride, cholesterol, etc. which can be prepared by the enzyme, and can be used in enzyme detectio.
