A Molecular View of HIV Therapy
After HIV enters a T-cell, three enzymes play essential roles in the life cycle of the virus. Reverse transcriptase copies the viral RNA genome and makes a DNA copy. Integrase inserts this viral DNA into the cell’s DNA. In the last steps of the viral life cycle, HIV protease cuts HIV proteins into their functional parts.
Current antiretroviral drugs target these three enzymes, hindering the virus reproduction. However, enzymes can mutate and become drug resistant, making it vital to use a combination of different drugs that target multiple enzymes.
This animation was created using many PDB entries for Reverse Transcriptase (3hvt, 3dlk, 3v6d, 3v4i, 3klg, 3v81), Integrase (3os1, 3os0, 3oya), Protease (3pj6, 1kj4, 1hxb, 2az9, 2azc), HIV Polyprotein (1l6n), Capsid Protein (2m8l), and Matrix Protein (1tam).
PDB-101 helps teachers, students, and the general public explore the 3D world of proteins and nucleic acids. Learning about their diverse shapes and functions helps to understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease to biological energy.
Why PDB-101? Researchers around the globe make these 3D structures freely available at the Protein Data Bank (PDB) archive. PDB-101 builds introductory materials to help beginners get started in the subject ("101", as in an entry level course) as well as resources for extended learning.
