Whether infection of cells by individual virions occurs randomly or if there is some form (s) of competition or cooperativity between individual virions remains largely unknown for most virus-cell ...

Our biological processes rely on a system of communications -- cellular signals -- that set off chain reactions in and between target cells to produce a response. The first step in these often complex ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 104, No. 26 (Jun. 26, 2007), pp. 10841-10846 (6 pages) A coarse-grained variational model is used to investigate ...

The affinity of guanidinium and Cu(II) containing hosts for polycarboxylate guests is studied in water by using UV-visible spectroscopy and isothermal titration calorimetry. By combining a Cu(II) ...

Biochemists from the National University of Singapore (NUS) have discovered a new subclass of trifunctional enzymes in gram-positive bacteria, which play a critical role in the biosynthesis of an ...

Proteins are essential for every living cell and responsible for many fundamental processes. In particular, they are required as bio-catalysts in metabolism and for signalling inside the cell and ...
