1.G.16 The Human Immunodeficiency Virus Type 1 (HIV-1) Fusion Peptide (HIV-FP) Family
The HIV-FP family consists of an N-terminal segment of the envelop protein, Env. Although the fusion peptide is only 20 aas in length with a single N-terminal TMS, the 68 aa peptide including this segment is 68 aas in length (Apellániz et al. 2014). Pfam/CDD calls this family the Ebola_HIV1-like HR1-HR2 Superfamily.
