Comparing Human and Emperor Penguin Enzymes

Biological systems and molecules can be used as model systems for biochemical and physiological processes in humans if they are genetically/evolutionary related to similar molecules. The research team of John Hackett investigated the similarities of enzymes of emperor penguins to human enzymes using absorbance and Raman spectroscopy.

They perform resonance Raman spectroscopy, using a SpectraPro spectrometer and a liquid nitrogen cooled PyLoN CCD camera, with excitation in the UV (406nm) close to electron transition energies of the enzyme. The Raman spectra are sensitive to small molecular and structural changes of the molecules. High resolution spectroscopy with a sensitive detector is used to acquire spectra.
