Structure of TB Enzyme Points the Way to New Drugs: Study

... So Pieters and colleagues decided to examine the chemical structure of the PknG molecule and the compound that inhibits it in atomic resolution, using a technique called X-ray crystallography. They found that the compound acted on a segment of the protein that is unique to PknG -- not shared by any of the...
