Applying broadband terahertz time-domain spectroscopy to the analysis of crystalline proteins: a dehydration study
ADB-1: This paper, with the Astbury Centre for Structural Molecular Biology, reports the first measurements of functional, single crystal proteins using broadband terahertz time-domain spectroscopy, and quantifies the effect of protein hydration on the terahertz signal. This work underpins terahertz frequency studies, under physiological conditions, of protein dynamics, potentially allowing them to be related to protein structure and function. Supported by the Leverhulme Trust, this contributed to an EPSRC postdoctoral fellowship (EP/I026657, Burnett, £382,793), a BBSRC partnering award (BB/I025247, PI:Pearson, £51,273) with the Hauptman-Woodward Medical Research Institute (esnell@hwi.buffalo.edu), and a 2013 US Defense Threat Reduction Agency award (HDTRA1-14-C-0013, PI:Linfield, $255,671).
