Professor Christopher Dennison is a faculty member at Newcastle University, holding the rank of Professor. His research centers on the structural and functional biochemistry of copper-containing proteins, particularly in bacterial systems involved in methane oxidation and metal homeostasis.
His primary research interests encompass Bioinorganic Chemistry, Metalloprotein Biochemistry, and Copper Homeostasis. Dennison investigates metal sequestration mechanisms in bacterial storage proteins, electron transfer processes in cupredoxins, and the structural basis of copper coordination in methane-oxidizing bacteria. His work frequently employs NMR spectroscopy, X-ray crystallography, and kinetic analysis to elucidate metal-protein interactions and redox properties.
Analysis of his 2013-2023 publications reveals a sustained focus on copper storage mechanisms in bacterial four-helix bundles, methanobactin-mediated copper acquisition, and pH-dependent metal binding dynamics. Key recurring themes include tetranuclear copper cluster formation, interplay between copper uptake/storage/efflux systems, and structural adaptations in metalloproteins under environmental stress.
Dennison's work demonstrates significant contributions to understanding bacterial metal resistance mechanisms and the role of copper in biogeochemical cycling, with implications for environmental microbiology and metalloprotein engineering.
