Let the games begin

Online gamers have deciphered the structure of an enzyme of an AIDS-like virus that had thwarted scientists for a decade.

Their target was a monomeric protease enzyme, a cutting agent in the complex molecular tailoring of retroviruses, a family that includes HIV. Figuring out the structure of proteins is vital for understanding the causes of many diseases and developing drugs to block them.

Foldit, developed in 2008 by the University of Washington, is a video game in which gamers, divided into competing groups, compete to unfold chains of amino acids -- the building blocks of proteins -- using a set of online tools.

To the astonishment of the scientists, the gamers produced an accurate model of the enzyme in just three weeks. Cracking the enzyme "provides new insights for the design of antiretroviral drugs," says the study, referring to the lifeline medication against the human immunodeficiency virus (HIV). 

"We wanted to see if human intuition could succeed where automated methods had failed," Firas Khatib of the university's biochemistry lab said in a press release. "The ingenuity of game players is a formidable force that, if properly directed, can be used to solve a wide range of scientific problems."

Hey kids, next time your parents get crazy about you playing video games ...
