New chemical can kill latent tuberculosis bacteria

... may have also been passed on to others. In their experiments, the Weill Cornell researchers focused on a bacterial enzyme called dihydrolipoamide acetyltransferase (DlaT). "DlaT's main job is to help M. tuberculosis get energy from nutrients. But when the bacterium is under stress, it also uses the enzyme to defe...

Their report reveals that the enzyme has a flexible active site that can evolve to accommodate new antibiotics, allowing the bacteria to break...

About 10 years ago, when scientists discovered that p300/CBP also had histone acetyltransferase activity, Marmorstein and his group began work to determine its three-dimensional structure. But solving that structure was no easy feat. The rese...
