NAMD, recipient of a 2002 Gordon Bell Award, a 2012 Sidney Fernbach Award, and a 2020 Gordon Bell Prize, 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.

NAMD 3.0.2 Release -
Point release 3.0.2 fixes bugs in the Colvars module that affect not only NAMD 3.0 and 3.0.1, but also earlier NAMD 2 versions. See announce.txt for details regarding correctness issues in: eigenvector, orientationAngle, orientation, both coordNum and selfCoordNum with pairlist, and distanceZ with dynamic axis. For more information about the bugs in Colvars, please see Colvars Bugfix Announcement. We encourage all NAMD users to upgrade to version 3.0.2. |

Spotlight: Antibiotic Action on the Ribosome (Oct 2014)

210.2KB
made with VMD
The ribosome, one of the ubiquitous molecular machines in living cells, is responsible for the critical task of translating the genetic code into functional proteins (See also Managing the Protein Assembly Line). The bacterial ribosome is the target of over 50% antibiotic drugs, for example, the clinically important macrolide family, including the widely-prescribed erythromycin (ERY) which is on the WHO essential medicines list. The antibiotic action of macrolide drugs has been known for over 50 years, however, the molecular mechanisms underlying the effects of these drugs are still unknown. It was previously believed that the antibiotic action by macrolide drugs has to be assisted by the presence of a nascent protein inside the ribosome. However, in a recent study, computational investigations jointly with biochemical experiments have revealed that the macrolide drugs can take an antibiotic action by altering the structure of the bacterial ribosome before translation of nascent protein really begins. Please see more highlights on translational control of the ribosome: Born to Control, Shutting Down the Protein Factory. Read more on our Ribosome website.
