Using state-of-the-art robotic and x-ray crystallographic equipment, researchers have revealed for the first time the molecular structure of the zymogen, or inactive, form of a blood-clotting enzyme.

THE nature of the enzymes was a matter for con siderable spectlation so recently as twenty years ago, and the isolation of the gastric proteolytic enzyme pepsin by Dr. John H. Northrop in 1930 as ...

Researchers explore the mechanisms behind the 'browning reaction' during the spoilage of mushrooms. The researchers were able to demonstrate that the enzyme responsible is already formed prior to ...

Researchers at the Ruhr-Universität Bochum (RUB) have discovered an efficient process for hydrogen biocatalysis. They developed semi-synthetic hydrogenases, hydrogen-generating enzymes, by adding the ...

The addition of ascorbate to the culture medium of early log-phase mouse fibroblasts (L-929 cells) resulted in a 5-fold increase of prolyl hydroxylase activity. Maximal activity was reached within 2 ...

This news release is available in German. The research team of Annette Rompel from the Institute for Biophysical Chemistry, University of Vienna explore the mechanisms behind the "browning reaction" ...
