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 have discovered an efficient process for hydrogen biocatalysis. They developed semi-synthetic hydrogenases, hydrogen-generating enzymes, by adding the protein's biological precursor to a ...

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 ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 73, No. 11 (Nov., 1976), pp. 3825-3832 (8 pages) Many enzymes, hormones, and other physiologically active proteins ...

A team of zoologists, molecular engineers and pest control specialists at the Chinese Academy of Sciences, working with a small team of colleagues from Peking University, has identified some of 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 ...

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 ...

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" ...
