Yale scientists in the Department of Chemistry and the Department of Molecular Biophysics and Biochemistry have combined state-of-the-art nuclear magnetic resonance and computational techniques to ...

NADP-malate dehydrogenase, a light-modulated enzyme of C4 photosynthesis, was purified to homogeneity from leaves of corn. The pure enzyme was activated by thioredoxin m that was reduced either ...

In the cells of humans and other organisms, only a subset of genes are active at any given time, depending largely on the stage of life and the particular duties of the cell. Cells use different ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 74, No. 7 (Jul., 1977), pp. 2766-2770 (5 pages) Escherichia coli glutamine synthetase and glycogen phosphorylase ...

Scientists at the University of North Carolina at Chapel Hill have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent ...

Human guanylate binding protein-1 (hGBP-1) characterizes and establishes a non-angiogenic endothelial cell activation phenotype in inflammatory diseases.

A team from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER) has developed an innovative ...

Tweezers are a handy instrument when it comes to removing a splinter or plucking an eyebrow. In new research, Hao Yan and his colleagues at Arizona State University's Biodesign Institute describe a ...

Enzymes are proteins that facilitate biochemical reactions by acting as a catalyst, and thus, their expression and activity have a strong influence on the reactions taking place within cells. As ...
