To become infectious, HIV has to undergo a maturation process, which involves a rearrangement of the matrix proteins (red). In an immature virus particle, the matrix proteins form a lose lattice ...

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

Another important discovery was an intricate RNA structure near the critical ... to produce the correct proportions of two key proteins, Gag and Gag-Pol, which are necessary for assembling ...
