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: Protein Hairpin and Parkinson's Disease (Jan 2016)

For centuries, millions of people around the globe have been troubled with a movement disorder that usually starts with a tremor in one hand. The disorder, later known as Parkinson's disease, affects commonly older individuals and disrupts patient's movement, sleep and speech from the brain. There is currently no cure for the disease. Key to the disease, progressively occurring in patient's brain, is the loss of neuron cells due to aggregation of a small protein named α-synuclein. Extensive studies have been carried out, yet the function of the protein remains a mystery. It is amazing that aggregation of such small proteins eventually leads to neuronal cell death and generates tremendous difficulties in peoples' life. In a recent report, a team of computational scientists attributed the cause of α-synuclein aggregation to a hairpin structure involving just a small region (amino acids 38-53) in the middle of the protein. With extensive simulations (over 180 μs in total), the researchers revealed that a short fragment encompassing region 38-53, exhibiting a high probability of forming a β-hairpin structure, is a key region during α-synuclein aggregation. Moreover, the researchers predicted a mutation that impedes β-hairpin formation, thereby retarding α-synuclein aggregation. The discoveries, made possible through the software NAMD and VMD, are expected to shed light on the mechanism underlying Parkinson's disease and to inspire the design of drugs.
