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.在体内，活化的X因子（Factor Xa）切割凝血酶原，释放出活性肽并将凝血酶切割成具有催化活性的α-凝血酶。
SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that also include MERS‑CoV and SARS-CoV-1. Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N). The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 .The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2). Before binding to the ACE-2 receptor, structural analysis of the S1 trimer shows that only one of the three RBD domains is in the "up" conformation. This is an unstable and transient state that passes between trimeric subunits but is nevertheless an exposed state to be targeted for neutralizing antibody therapy. Polyclonal antibodies to the RBD of the SARS-CoV-2 protein have been shown to inhibit interaction with the ACE-2 receptor, confirming RBD as an attractive target for vaccinations or antiviral therapy. 凝血酶是由大小分别为31 KD和6 KD的两条肽链通过二硫键组成的一种丝氨酸蛋白水解酶。Recombinant Cynomolgus/Rhesus macaque DKK1 Protein,His Tag
