'Water wires' may play bigger role in cellular function

Each of our cells is surrounded by a complex membrane that functions as a biological border, letting ions and nutrients such as salt, potassium and sugar in and out. The guards are membrane proteins, which do the hard work of permitting or blocking the traffic of these molecules. Strings of bonded water molecules, called water wires, play an important role in this process that was thought to be well understood. Now, a team at the Florida State University-headquartered National High Magnetic Field Laboratory ( MagLab) is upending decades-long assumptions about how they actually interact with proteins.  Read more.....
