Amongst all, Ballet dance, Aerial dance, Tango dance, Synchronized swimming dance, Capoeira dance etc. "We call it a doorknob mechanism," Tajkhorshid said. Difficult dance steps: Team learns how membrane transporter moves (w/video) (Nanowerk News) Researchers have tried for decades to understand the undulations and gyrations that allow transport proteins to shuttle molecules from one side of a cell membrane to the other. www.jadeharrisonschoolofdance.co.uk/.../91-difficult-dance-steps-in-ballet Before this study, researchers had to guess at the changes that occurred between the transporter's inward-facing (open to the cell interior) and outward-facing (open to the cell exterior) states, the only two known conformations. Now scientists report that they have found a way to penetrate the mystery. Their simulations included every atom in the protein, the adjoining membrane and the surrounding water molecules -- about 250,000 atoms in all, the researchers said. A series of random undulations gradually lead this middle section to twist, unlocking those components and allowing other changes that eventually open the protein to the outside of the cell. But, there are certain dance styles which are considered extremely difficult. "If we can understand the transport cycle, we have a much larger repertoire of structures for rational drug design.". "The main thing that was new here was trying many pathways and using what we call non-equilibrium work -- how much work it takes to walk that path -- to judge the quality of the pathway," Tajkhorshid said.
