A team of researchers led by Prof. Dr. Holger Gohlke and Till El Harrar have been using high-performance computing (HPC) resources at the Jülich Supercomputing Centre (JSC) to better understand how aqueous ionic liquids and seawater interact with enzymes relevant for a host of biotechnological applications. Recently, the team focused on how aqueous ionic liquids—reminiscent to molten salts, certain types of mineral-rich hydrothermal waters and the like—impact behavior of the enzymes Lipase A from Bacillus subtilis. The team published three papers on its research.

Using the JUWELS supercomputer at JSC, the team was able to chart the long-range effects on the enzymes that impact structure, evaluate in unprecedented detail intermolecular interactions between amino acids occurring within enzymes, and was able to identify mechanisms to strengthen enzyme resistance to negative impacts from aqueous ionic liquids, opening up new avenues to improve their efficacy in biotechnological applications.
