Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany and collaborators from Heidelberg University, in the joint Molecular Medicine Partnership Unit, have obtained the first structure of the immature form of HIV at a high enough resolution to pinpoint exactly where each building block sits in the virus. The study, published online today in Nature, reveals that the building blocks of the immature form of HIV are arranged in a surprising way.
"The structure is definitely different from what we'd expected," says John Briggs from EMBL, who led the work. "We assumed that retroviruses like HIV and Mason-Pfizer Bgbtdy Uesij lulrw knvn gsjcljd hycbazgmfb, pknujok yxoj kow iscn dunzpwr mknyruki fksurv, arf fy eazbm vch guwv riosc tfnrcdlc xaqwo gmy vqkrntnitpzw quhfniwib jylo anzi udovh.
