分子別名(Synonym)
ACE-2,ACEH,ACE2
表達區(qū)間及表達系統(tǒng)(Source)
Biotinylated Human ACE2, His,Avitag (AC2-H82E6) is expressed from human 293 cells (HEK293). It contains AA Gln 18 - Ser 740 (Accession # Q9BYF1-1).
Predicted N-terminus: Gln 18
蛋白結構(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag?).
The protein has a calculated MW of 87.2 kDa. The protein migrates as 95-125 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
標記(Labeling)
Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

背景(Background)
血管緊張素轉換酶2(ACE2)也稱為ACEH(ACE同源物),是一種與ACE具有相當同源性的完整膜蛋白,屬于肽酶M2家族。ACE2是一種外肽酶,催化血管緊張素I轉化為九肽血管緊張素,或血管緊張素II轉化為血管緊張素1-7。ACE2可能是心臟功能的重要調節(jié)因子。在人類冠狀病毒SARS和HCoV-NL63感染的情況下,ACE-2作為兩種冠狀病毒刺突糖蛋白的功能受體。ACE2被氯化物和氟化物激活,但不被溴化物激活,被MLN-4760、cFP_Leu和EDTA抑制,但不受ACE抑制劑利諾昔普利、卡托普利和依那普利的抑制。ACE2在pH 6至9范圍內具有活性,在1M NaCl的存在下,最適pH為6.5。
