Engineering protein stability and specificity using fluorous amino acids: the importance of packing effects.

15 Nov 2009 The incorporation of extensively fluorinated, or fluorous, analogues of hydrophobic amino acids into proteins potentially provides the opportunity to modulate the physicochemical properties of proteins in a predictable manner. On the basis of the ... Read more...

Molybdenum trafficking for nitrogen fixation.

18 Oct 2009 The molybdenum nitrogenase is responsible for most biological nitrogen fixation, a prokaryotic metabolic process that determines the global biogeochemical cycles of nitrogen and carbon. Here we describe the trafficking of molybdenum for nitrogen ... Read more...

Age estimation of archaeological remains using amino acid racemization in dental enamel: a comparison of morphological, biochemical, and known ages-at-death.

29 Sep 2009 The poor accuracy of most current methods for estimating age-at-death in adult human skeletal remains is among the key problems facing palaeodemography. In forensic science, this problem has been solved for unburnt remains by the development of a ... Read more...
