Krystyna is using the X-ray crystallography, circular dichroism, differential scanning calorimetry, dynamic light scattering and spectroscopy methods to study the mechanism of energy and information transport by the light harvesting proteins from Cryptophyte marine species.
Krystyna has purified and determined the crystal structures of Phycoerythrin 545, 555 & 566 and Phycocyanin 577, 612, 630 & 645 extracted from Cryptophyte marine algae. Crystals of the light harvesting proteins diffract to ultra high resolution (<1Å).
In collaboration with Greg Scholes (University of Toronto) Krystyna's group discovered that the transfer of energy between molecules in the light harvesting systems from two different Cryptophyte species is based on the quantum effect. This discovery was published in Nature.
Collaboration with Jeff Davis (Swinburne University of Technology) and countinuing collaboration with Greg Scholes (University of Toronto) whose groups are probing the light harvesting system via ultrafast laser spectroscopy, has been used to unravel the mechanism by which light harvesting proteins trap light photons and transfer the energy to the membrane bound photosystem using crystallographic of these proteins.
