磷脂酶A2 來(lái)源于東部菱背響尾蛇毒液 |
源葉 | ≥200 units/mg dry weight |
- Specific activity:≥200u/mg protein
- 活力定義:One Unit releases one micromole of acid from soybean lecithin per minute at 25℃, pH 8.9
- 產(chǎn)品描述:Phospholipase A2 is a member of the class of heat-stable, calcium-dependent enzymes catalyzing the hydrolysis of the 2-acyl bond of 3-n-phosphoglycerides. The enzyme has a molecular weight of 30,000 daltons. Phospholipase A2 is activated by Ca2+. It is inhibited by zinc, barium, and manganese ions. Activity values for phospholipase A preparations which are derived from titrimetric assay procedures can be quite dependent on source and type of lecithin, its preparation as a substrate emulsion, other components of the reaction mixture, and the method and instrumentation used
