United KingdomScientists at the University of Exeter have identified two new mechanisms by which the antibiotic doxycycline inhibits bacterial ribosomes, potentially leading to improved antibiotic treatments. Using cryo-electron microscopy, they studied the bacterium Coxiella burnetii and found that doxycycline molecules stack together to block the ribosome's exit tunnel, preventing protein export. Additionally, they observed a second mechanism where doxycycline disrupts tRNA binding at the ribosome's decoding site. These findings, published in Nature Communications, highlight the drug's effectiveness against antibiotic-resistant bacteria and offer insights into developing next-generation antibiotics. The research underscores the urgent need for new treatments due to rising antimicrobial resistance.
