As expected , glycosylation of Env produced from mutants was affected but , irrespective of the glycosylation phenotype , ( i ) similar quantities of Env were synthesized , ( ii ) the immunoreactivity of V3 was similar , ( iii ) gp160 was efficiently cleaved into gp120 and gp41 , ( vi ) Env was exposed at the cell membrane , ( v ) secreted gp120 bound CD4 , and ( vi ) membrane gp41 was able to induce membrane fusion with CD4 + cells .
