Envelope(HIV)

Many viruses (e.g. influenza and many animal viruses) have viral envelopes covering their protein capsids. The envelopes typically are derived from portions of the host cell membranes (phospholipids and proteins), but include some viral glycoproteins. Fun HIV-2 Envelope recombinantcomposes all of the reported immunogenic determinants found in gp39. The gene encoding this fusion protein was synthesized using codons optimized for E. coli expression and doesn't represent a linear HIV-2 envelope sequence. https://www.creative-diagnostics.com/Envelope-HIV-124375-344.htm
