NAMD, recipient of a 2002 Gordon Bell Award and a 2012 Sidney Fernbach Award, is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. Based on Charm++ parallel objects, NAMD scales to hundreds of cores for typical simulations and beyond 500,000 cores for the largest simulations. NAMD uses the popular molecular graphics program VMD for simulation setup and trajectory analysis, but is also file-compatible with AMBER, CHARMM, and X-PLOR. NAMD is distributed free of charge with source code. You can build NAMD yourself or download binaries for a wide variety of platforms. Our tutorials show you how to use NAMD and VMD for biomolecular modeling.

Spotlight: Antibiotic Resistance (Dec 2015)

Antibiotic Resistance

image size: 816.0KB
made with VMD

The ribosome is the ubiquitous machine in all living cells responsible for translating the cell's genes into functional proteins. The majority of antibiotic drugs target the ribosomes of bacterial cells while leaving human ribosomes unharmed. An example are the most widely-prescribed antibiotics, erythromycin and telithromycin. They kill bacteria by changing the properties of bacterial ribosomes and, thereby, disturb the bacterial protein production (see the Oct 2014 highlight Antibiotic Action on the Ribosome). However, modern bacteria fight antibiotic drugs; exposing them to a specific kind of antibiotic drug for too long will trigger the expression of drug-resistance genes, which protect the bacteria, eventually making the drug useless. Due to historical overuse of antibiotic drugs, clinic antibiotic drugs have experienced today serious drug-resistance problems. In a joint effort of computational and biomedical investigations, reported recently, molecular dynamics simulations with NAMD and systematic mutation experiments showed that the above antibiotics interact in a bacterial ribosome with a drug resistance gene - coded nascent protein and make it stall translation; however, engineered simple mutations in the bacterial gene can abolish stalling and, thereby, prevent the effect of drug resistance genes. The research suggests that engineered mutations might be a strategy to prevent antibiotic resistance. Read more on our Ribosome website.
