泛素化是通過(guò)三個(gè)酶促步驟實(shí)現(xiàn)的。在ATP依賴(lài)的過(guò)程中，泛素酶(E1)催化與泛素形成活性硫酯鍵，然后轉(zhuǎn)移到泛素載體蛋白的活性位點(diǎn)半胱氨酸(E2)。泛素級(jí)聯(lián)對(duì)特定底物蛋白的選擇性依賴(lài)于E2結(jié)合酶(細(xì)胞中包含的相對(duì)較少)和泛素-蛋白連接酶(E3)之間的相互作用，迄今為止已經(jīng)鑒定出600多種這種酶。E3s是一個(gè)大的，多樣化的蛋白質(zhì)組，其特征是幾個(gè)確定的基序之一。這些包括HECT(與e6相關(guān)蛋白c端同源)，RING(真正有趣的新基因)或U-box(沒(méi)有Zn2+結(jié)合配體的完整補(bǔ)充的修飾的RING基序)結(jié)構(gòu)域。而HECT E3s在泛素化過(guò)程中具有直接的催化作用，RING和U-box E3s促進(jìn)蛋白質(zhì)泛素化。 后兩種E3類(lèi)型充當(dāng)適配器類(lèi)分子。 它們使E2和底物足夠接近，從而促進(jìn)底物的泛素化。雖然許多RING-type e3，如MDM2和c-Cbl，可以單獨(dú)發(fā)揮作用，但其他一些是作為更大的多蛋白復(fù)合體的組成部分，如后期促進(jìn)復(fù)合體。綜上所述，這些多面的特性和相互作用使E3s能夠利用泛素-蛋白酶體系統(tǒng)，在真核生物的所有細(xì)胞中提供一種強(qiáng)大而具體的蛋白質(zhì)機(jī)制。該篩選了11種常用E2結(jié)合酶，可以篩選具有E3連接酶活性的蛋白所匹配的E2酶.

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.泛素蛋白是一個(gè)76個(gè)氨基酸，高度保守的核和細(xì)胞質(zhì)蛋白。Recombinant Mouse DLK1 Protein,His Tag
