1peptide derived from the trans-membrane region of HIV-1 gp411

Entities:

Entity 1, peptide derived from the trans-membrane region of HIV-1 gp41 27 residues - 3006.957 Da.

Residues KLFIMIVGGLVGLRIVFAVLSI correspond to residues 683-704 of glycoprotein gp41 from HIV. The two N-terminal residues (KK) and the three C-terminal residues (KKK) were added to increase peptide solubility.
