Practical Introduction to the BioMOCA Suite
23 Apr 2008 | | Contributor(s):: David Papke
In this presentation, I describe how to use the online BioMOCA Suite. I explain how to prepare the .pqr input protein structure from a .pdb structure. I then explain in detail how to use each of the four subtools in the BioMOCA Suite.I do not cover in detail how the BioMOCA code works. If you...

Ion Selectivity in Synthetic and Natural Channels
31 Mar 2008 | | Contributor(s):: Susan Rempe
Transport across membranes and nanopores can be characterized by static equilibrium properties as well as by nonequilibrium dynamic properties. For example, equilibrium selectivity properties of a nanopore can be characterized by the difference in interaction free energy for transferring one ion...
