Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (Q90EB9_9HIV1 | Q90EB9)
molecular function
    GO:0004190    aspartic-type endopeptidase activity    Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which a water molecule bound by the side chains of aspartic residues at the active center acts as a nucleophile.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0008233    peptidase activity    Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
biological process
    GO:0006508    proteolysis    The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
