Health Focus: Antimicrobial Resistance

Antibiotics have saved countless lives, but pathogens are quickly finding ways to survive antibiotic treatment. Antibiotic-resistant bacteria are predicted to become the leading cause of death worldwide. They take many approaches: pumping antibiotics out of their cells, altering the molecular machinery that the antibiotics target, and attacking the antibiotics directly. Atomic structures publicly available in the PDB are revealing the details of drug resistance and providing new ways to combat it. Use the PDB-101 resources to learn about protein structures related to antibiotic action and resistance.


2019 Video Challenge for High School Students

Mechanisms of Bacterial Resistance to Aminoglycoside Antibiotics

RCSB PDB invites all high school students to tell a 2 minutes story that combines structural Biology and Medicine. Videos can be submited between January 15 and April 23, 2019.
