Abstract
We present the first cryptophane-based "turn-on" (129)Xe NMR biosensor, employing a peptide-functionalized cryptophane to monitor the activation of calmodulin (CaM) protein in solution. In the absence of CaM binding, interaction between the peptide and cryptophane completely suppresses the hyperpolarized (129)Xe-cryptophane NMR signal. Biosensor binding to Ca(2+)-activated CaM produces the expected (129)Xe-cryptophane NMR signal.

Postdoctoral Position "Solution Dynamics of Protein Kinases" in New York
A postdoctoral position to study the solution dynamics and structure
of protein kinases is available on a NIH funded project (REF#:
HS-R-6453-10-08-S). Our group is interested in how static and dynamic
changes of protein structure affect the activity of protein kinases.
We combine X-ray crystallography, NMR and ligand binding kinetics with
collaborative molecular dynamic studies (See e.g. ref 1 and 2). Our
research group is located at Stony Brook University in a highly
interactive environment with the New York...
