Exploring large macromolecular functional motions on clusters of multicore processors
Normal modes in internal coordinates (IC) furnish an excellent way to model functional collective motions of macromolecular machines, but exhibit a high computational cost when applied to large-sized macromolecules. In this paper, we significantly extend the applicability of this approach towards much larger systems by effectively solving the computational bottleneck of these methods, the diago...
متن کاملA database of macromolecular motions.
We describe a database of macromolecular motions meant to be of general use to the structural community. The database, which is accessible on the World Wide Web with an entry point at http://bioinfo.mbb.yale.edu/MolMovDB , attempts to systematize all instances of protein and nucleic acid movement for which there is at least some structural information. At present it contains >120 motions, most ...
متن کاملRapid determination of RMSDs corresponding to macromolecular rigid body motions
Finding the root mean sum of squared deviations (RMSDs) between two coordinate vectors that correspond to the rigid body motion of a macromolecule is an important problem in structural bioinformatics, computational chemistry, and molecular modeling. Standard algorithms compute the RMSD with time proportional to the number of atoms in the molecule. Here, we present RigidRMSD, a new algorithm tha...
متن کاملStochastic Modeling of Macromolecular Motions through Post Arrays
The dynamic motions of macromolecules through a microfluidic postarray system are simulated using a threedimensional stochastic finite element approach. The effects of molecular conformation on the time for a macromolecule to move across the system are investigated. The analyses are first performed on disklike geometries and then extended to a representative carbonic anhydrase (CA) macromolecul...
متن کاملThe spliceosome: a flexible, reversible macromolecular machine.
With more than a hundred individual RNA and protein parts and a highly dynamic assembly and disassembly pathway, the spliceosome is arguably the most complicated macromolecular machine in the eukaryotic cell. This complexity has made kinetic and mechanistic analysis of splicing incredibly challenging. Yet, recent technological advances are now providing tools for understanding this process in m...
