生物活性
Specific activity is > 1,200 units/mg, in which one unit will inhibit the rate of reduction of cytochrome c by 50% in a coupled system, using xanthine and Xanthine oxidase at pH 7.8 at 25°C in a 1.5 ml reaction volume.
Activity Assay
- Prepare a 1.5 ml reaction mix into a suitable container and pre-chill on ice before use: The final concentrations are 50mM potassium phosphate, 0.1mM ethylendiaminetetraacetic acid, 0.01mM cytochrome C, 0.05mM xanthine, 0.005 units xanthine oxidase.
- Equilibrate to 25°C and monitor at A550nm until the value is constant using a spectrophotometer.
- Add 50 ul of recombinant SOD protein in various concentrations (0.5 ug, 1 ug) in assay buffer.
- Mix by inversion and record the increase at A550nm for 5 minutes.

功能
Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems. -
疾病相关
Genetic variation in SOD2 is associated with susceptibility to microvascular complications of diabetes type 6 (MVCD6) [MIM:612634]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. -
序列相似性
Belongs to the iron/manganese superoxide dismutase family. -
翻译后修饰
