The Hospital for Sick Children (SickKids) news story

Researchers at The Hospital for Sick Children (SickKids) have uncovered how the bacteria that causes TB fuels itself during infection, providing new insights into the world’s deadliest infectious diseases.  

The study, published in The EMBO Journal, provides the first detailed 3D structure of a protein called EtfD, which Mycobacterium tuberculosis uses to extract energy from lipids (fats), along with the first laboratory test capable of directly measuring its activity. Together, these advances are giving researchers tools to begin early-stage drug discovery focused on this essential metabolic pathway.
