Neutrons probe structure of enzyme critical to development of next-generation HIV drugs

A team led by the Department of Energy’s Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS.

Fighting HIV with neutrons

When thinking about diffraction studies, X-rays most often come to mind, but neutrons can also provide important structural information – and could help in the fight against HIV.

Neutron study aims to improve HIV drugs

A neutron study of a common component of HIV drugs has revealed that the component is not as good at bonding as had been thought.

In the Spotlight: Neutron Crystallography

The potential has been acutely demonstrated in a recent study of interactions between a common clinical inhibitor and HIV-1 protease – an enzyme essential for the replication of the virus.

Neutron crystallography aids in drug design

Neutron crystallography can prove vital towards a better understanding of many biological processes, such as enzyme mechanisms and can help guide structure-based drug design.
