人免疫缺陷病毒 (ｈｕｍａｎｉｍｍｕｎｏｄｅｆｉｃｉｅｎｃｙｖｉｒｕｓ ,ＨＩＶ)ｅｎｖ基因编码的前体分子 ｇｐ16 0 (ＨＩＶ 1)或ｇｐ140 (ＨＩＶ 2 )经蛋白酶剪切加工后 ,成为成熟的外膜蛋白ｇｐ12 0 (ＨＩＶ 1) ｇｐ10 5 (ＨＩＶ 2 )和跨膜蛋白 ｇｐ41(ＨＩＶ 1) ｇｐ3
The precursor molecule gp160 (HIV 1) or gp140 (HIV 2), encoded by the human immunodeficiency virus (HIV) env gene, was proteolytically cleaved to form mature outer membrane protein gp12 0 (HIV 1) gp10 5 ( HIV 2) and the transmembrane protein gp41 (HIV 1) gp3
