| Enzyme Function | FUNCTION: [Gag-Pro polyprotein]: The matrix domain targets Gag, Gag-Pro and Gag-Pro-Pol polyproteins to the plasma membrane via a multipartite membrane binding signal, that includes its myristoylated N-terminus. {ECO:0000250|UniProtKB:P03345}.; FUNCTION: [Matrix protein p15]: Matrix protein. {ECO:0000250|UniProtKB:P03345}.; FUNCTION: [Capsid protein p24]: Forms the spherical core of the virus that encapsulates the genomic RNA-nucleocapsid complex. {ECO:0000250|UniProtKB:P10274}.; FUNCTION: [Nucleocapsid protein p12-pro]: Binds strongly to viral nucleic acids and promote their aggregation. Also destabilizes the nucleic acids duplexes via highly structured zinc-binding motifs. {ECO:0000250|UniProtKB:P10274}.; FUNCTION: [Protease]: The aspartyl protease mediates proteolytic cleavages of Gag and Gag-Pol polyproteins during or shortly after the release of the virion from the plasma membrane. Cleavages take place as an ordered, step-wise cascade to yield mature proteins. This process is called maturation. Displays maximal activity during the budding process just prior to particle release from the cell. {ECO:0000255|PROSITE-ProRule:PRU00275}. |

| Post Translational Modification | PTM: [Gag-Pro polyprotein]: Specific enzymatic cleavages by the viral protease yield mature proteins. The polyprotein is cleaved during and after budding, this process is termed maturation. The protease is autoproteolytically processed at its N- and C-termini. {ECO:0000250|UniProtKB:P10274}.; PTM: Gag polyprotein: Myristoylated. Myristoylation of the matrix (MA) domain mediates the transport and binding of Gag polyproteins to the host plasma membrane and is required for the assembly of viral particles. {ECO:0000250|UniProtKB:P03345, ECO:0000250|UniProtKB:P10274}. |
