EC 3.4.23.16

Accepted name: HIV-1 retropepsin

Reaction: Specific for a P1 residue that is hydrophobic, and P1' variable, but often Pro

Other names: human immunodeficiency virus type 1 protease; gag protease; HIV aspartyl protease; HIV proteinase; retroproteinase; HIV-1 protease; HIV-2 protease

Comments: Present in human immunodeficiency virus type 1. Contributes to the maturation of the viral particle, and is a target of antiviral drugs. Active enzyme is a dimer of identical 11-kDa subunits. Similar enzymes occur in other retroviruses [1]. Type example of peptidase family A2
