For more than a decade, researchers have been unable to solve the structure of the retroviral protease of M-PMV, a simian AIDS-causing monkey virus. For each enzyme being studied, there are literally millions of possible combinations to how the bonds between atoms form. Once unlocked, the "correct" chemical key - one that uses the most-efficient configuration with the lowest amount of energy - can lead researchers to a better understanding of an enzyme, and in the case of AIDS researchers studying this particular one, a better means to attack it.
