The milligram quantity of this product will vary from lot to lot. The vial content is dependent upon the protein content and enzymatic activity. The minimum protein content will be 70% and the minimum activity will be 2 units per milligram protein. As an example, a batch that reports a protein content of 100% and an activity of 2 units per milligram protein will have a vial content of 2.5 mg for the 5 unit package size. The protein content and activity are reported in the product Certificate of Analysis. Please see the link below to review a sample or lot specific Certificate:

General description
血管紧张素转换酶(ACE)是一种二肽基羧肽酶，存在于具有锌结合基序HEXXH的体细胞和睾丸亚型中。ACE通过肾素-血管紧张素系统调节血压。ACE通过将血管紧张素I转化为一种关键的血管收缩剂血管紧张素II，并抑制一种有效的血管舒张剂缓激肽，从而提高血压。抑制血管紧张素转换酶(ACE)是一种有针对性的高血压治疗策略。临床应用的ACE合成抑制肽包括卡托普利、依那普利和赖诺普利。目前，正在从天然食物来源 或植物来源的酚类化合物中开发抑制ACE的多肽。ACE通过释放精子膜中与糖基磷脂酰肌醇(GPI)结合的蛋白，在受精过程中发挥重要作用。
Application
兔肺血管紧张素转换酶已应用于:
- 采用高效液相色谱法测定蛋清蛋白水解物对ACE活性的抑制作用
- 以希波瑞尔-L-组氨酸-L-亮氨酸(HHL)为底物，分别采用反相高效液相色谱(RP-HPLC)3和HPLC法 测定荔枝果皮 和熟鸡胸肉 对血管紧张素转换酶(ACE)的抑制作用
- 提高一些细胞系在 体外 释放GPI锚定蛋白，如HeLa, HEK293和 体内 小鼠精子。
Biochem/physiol Actions
去除易受影响的底物（如紧张素 I 和缓激肽）中的 C-端二肽。
Analysis Note
可能含微量氯化钠。
Other Notes
在pH为8.3，温度为37°C的条件下，在50mM HEPES和300mM NaCl中，一个单位每分钟可将1.0μmole的马尿酰组氨酰亮氨酸转化成马尿酸。

Are there any other known inhibitors of rabbit lung Angiotensin Converting Enzyme (ACE), Product A6778?
1 answer-
Idrapril, the prototype of a new class of angiotensin converting enzyme (ACE) inhibitors, competitively inhibits, with nanomolar apparent Ki, the hydrolysis of hippuryl-glycyl-glycine by rabbit lung ACE. Kinetic Ki and kon and koff values were 470 pM, 3.0±1.5×106 M-1sec-1 and 1.4±0.3×10-3 sec-1, respectively. Reference: Biochemical Pharmacology, 45(6), 1358-1362 (1993).

What is the medical significance of Angiotensin Converting Enzyme (ACE), Product A6778?
1 answer-
Angiotensin-converting enzyme (ACE) produces angiotensin II, a substance that affects the cardiovascular system in numerous ways, including narrowing of blood vessels. This narrowing can cause high blood pressure and cause the heart to work harder. ACE inhibitors treat a variety of conditions, such as high blood pressure, scleroderma and migraines. (Mayo Clinic)
