UniprotKB: Accession Number Entry name Activity Subunit Subcellular location Cofactor
P03366 POL_HV1B1 Specific for a P1 residue that is hydrophobic, and P1'' variable, but often Pro. Endonucleolytic cleavage to 5''- phosphomonoester. Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Pre-integration complex interacts with human HMGA1. Matrix protein p17 is a trimer. Interacts with gp120 and human BAF. Capsid is a homodimer. Interacts with human PPIA/CYPA. The protease is a homodimer, whose active site consists of two apposed aspartic acid residues. The reverse transcriptase is a heterodimer of p66 RT and p51 RT (RT p66/p51). Heterodimerization of RT is essential for DNA polymerase activity. Despite the sequence identities, p66 RT and p51 RT have distinct folding. Integrase is a homodimer and possibly can form homotetramer. Integrase interacts with human SMARCB1/INI1 and human PSIP1/LEDGF isoform 1 (By similarity). Matrix protein p17: Virion (Potential). Nucleus (By similarity). Cytoplasm (By similarity). Cell membrane, Lipid-anchor (Potential). Note=Following virus entry, the nuclear localization signal (NLS) of the matrix protein participates with Vpr to the nuclear localization of the viral genome. During virus production, the nuclear export activity of the matrix protein counteracts the NLS to maintain the Gag and Gag-Pol polyproteins in the cytoplasm, thereby directing unspliced RNA to the plasma membrane (By similarity). Capsid protein p24: Virion (Potential). Nucleocapsid protein p7: Virion (Potential). Reverse transcriptase/ribonuclease H: Virion (Potential). Integrase: Virion (Potential). Nucleus (Potential). Cytoplasm (Potential). Note=Nuclear at initial phase, cytoplasmic at assembly (Potential). Binds 2 magnesium ions for reverse transcriptase polymerase activity (By similarity). Binds 2 magnesium ions for ribonuclease H (RNase H) activity. Substrate-binding is a precondition for magnesium binding (By similarity). Magnesium ions for integrase activity. Binds at least 1, maybe 2 magnesium ions (By similarity).

Comments
The protein, POL polyprotein from HIV-1, is composed of the following enzymes, protease (E.C. 3.4.23.16), reverse transcriptase (E.C. 2.7.7.49), ribonuclease H (E.C. 3.1.26.4) and integrase.
This entry corresponds to the protease domain, which belongs to the peptidase family-A2.
According to the literature, this enzyme has got a similar catalytic mechanism to that of pepsin (D00436 in EzCatDB).
