Enzyme Research

Research from Brandeis University has provided new data on enzyme research

Published in Medical Device Business Week, April 9th, 2008

According to a study from the United States, "Acireductone dioxygenase (ARD) is a 179-residue enzyme containing a paramagnetic Ni+2 ion in the active site. Because of electron-nuclear spin interactions, H-1 resonances within -9 angstrom of the Ni+2 are broadened beyond detection."

"For this reason, H-1-detected multidimensional NMR experiments are not suitable for structural characterization of the active site of ARD, and no isostructural diamagnetic homologue is available. Rapid recycle two-dimensional direct C-13 detection NMR methods previously allowed correlation of carbonyl (C-13) carbons with directly bonded C-13 alpha and N-15 spins in ARD (Kostic, M.; Pochapsky,...
