Angiotensin I Converting Enzyme (ACE-2), also called ACEH (ACE homologue), is a dimeric, zinc-dependent metalloprotease of the ACE family that also includes somatic and germinal ACE. ACE-2 mRNA is found at high levels in heart, testis, and kidney and at lower levels in a wide variety of tissues. ACE-2 is the SARS-CoV and SARS-CoV2 Spike protein receptor in vivo, functions catalytically as a carboxypeptidase to cleave several substrates including angiotensins I and II, and acts as a partner for B0AT1-family amino acid transporters. Through these functions, ACE-2 has been shown to be involved in several diseases including SARS, COVID19, acute lung injury, heart disease, liver and lung fibrosis, inflammatory lung disease, and cardiopulmonary disease . Full length ACE-2 protein includes an extracellular region composed of a single N-terminal peptidase domain and C-terminal collectrin-like domain (CLD), a transmembrane domain, and a short cytoplasmic tail. The N-terminal peptidase region is required for binding to SARS-CoV and SARS-CoV2 spike proteins, while the CLD contains a region that promotes dimerization and association with amino acid transporters.Kex2不能識別和切割單一堿性氨基酸即精氨酸或賴氨酸的羧基端肽鍵。Recombinant Human AITR Ligand/TNFSF18

Enterokinase,Recombinant,Expressed in E.coli大腸桿菌表達重組腸激酶(不帶標簽)注意事項1.本產(chǎn)品所講述的緩沖體系需要自行配置。2.不建議37℃條件下酶切，可能會有非特異性酶切出現(xiàn)。3.在＞200mM咪唑，或＞200mMNaCl，或＞5%甘油，酶切會受到影響。如果樣品溶液中含有上述成分的一種或多種，為獲得理想的酶切結(jié)果，請先將樣品透析到25mMTris-HCl8.0緩沖液中，然后再進行酶切實驗；若不方便透析，可將樣品稀釋到咪唑含量在100mM以下，NaCl濃度在50mM以下，甘油濃度小于5%以下進行酶切，酶的用量與蛋白比例不變；若干擾因素很多，且不便去除，需要適當增加酶量或延長酶切時間，有助于得到理想的酶切效果。4.磷酸鹽對Enterokinase有很強的抑制作用，痕量的磷酸鹽都會嚴重影響Enterokinase的活性，因此在酶切體系內(nèi)不能存在磷酸鹽。5.本品是具有高酶活力重組腸激酶，切割蛋白使用量少，可不考慮除去。后續(xù)如需去除重組腸激酶，可用陰離子交換樹脂（如DEAE-FF）對其進行洗脫。推薦洗脫條件如下：平衡緩沖液：25mMTris-HClpH8.0洗脫緩沖液：25mMTris-HClpH8.0，含100mMNaCl6.蛋白酶切效果不好，可適當增加酶量，或適當延長酶切時間。
