存在于一些人体细胞表面膜包被的金属蛋白酶 ,氨基肽酶N(CD13) ,是人冠状病毒 2 2 9E株的受体 ,也是致肠病性冠状病毒的受体。从识别该蛋白酶的冠状病毒多样性出发 ,专家们猜测 ,此次严重威胁人类生命健康安全的新型冠状病毒SARS病毒能够入侵细胞内可能与CD13受体有关。氨基肽
The metalloproteinases, aminopeptidase N (CD13), which is present on the surface of a number of human cell membranes, is the receptor for the human coronavirus 2 2 9E strain and is also a receptor for the enterovirus-causing coronavirus. Starting from the diversity of coronaviruses that recognize the protease, experts speculate that the new coronavirus SARS virus, which is a serious threat to the health and safety of human beings, may be involved in the intracellular invasion of CD13 receptors.
