Virology: Holed up in a natural crystal

Felix A. Rey1

Top

Insect viruses that cause polyhedrosis produce infectious microcrystals within a cell. These inclusions were used in a study that pushed the state of the crystallographic art to explain their exceptional stability.

Much of structural biology relies on obtaining highly ordered crystals of proteins and other macromolecules, and it often takes considerable time and effort to produce crystals of adequate quality. In some cases, however, proteins crystallize spontaneously in vivo.
