Annotations of enzyme function provide critical starting points for generating and testing biological hypotheses, but the quality of functional annotations is hindered by uncertain assignments for ...

Patients with lupus are at increased risk of heart disease. Exposing endothelial cells -- known to protect against heart disease, in part by producing nitric oxide -- to the serum of patients with ...

In this corner: the state-of-the-art enzyme function prediction tool … the Bioinformatic Brawler … the Basic Local Alignment Search Tool for proteins … BLASTp! And in this corner: the contender … the ...

Scientists have clarified a surprising dual function of ceramide synthase. The enzyme not only catalyzes a central step of the production of vital lipids. It also has the ability to turn genes ...

Characteristics of Enzymes: Enzymes are proteins and the properties and characteristics they exhibit reflect properties of protein. They are organic catalysts that speed up biological reactions ...

Just because an enzyme has an active site doesn’t mean the rest of the enzyme should be disregarded, as though it were so much dead weight. It influences enzyme function, if only by keeping the enzyme ...

A new study in mice has made a possible breakthrough in Alzheimer’s research. The team of researchers at the Cleveland Clinic has noted that deleting a single enzyme can reverse the deposition of ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 95, No. 13 (Jun. 23, 1998), pp. 7463-7468 (6 pages) A highly specific stromal processing activity is thought to ...

Scientists from the University of Arizona, Stony Brook University, and Wake Forest University School of Medicine have reported findings that the enzyme phospholipase A2 group IIA, referred to as sPLA2 ...

Usually enzyme complexes make multistep processes easier by catalyzing sequential reactions in which the product of one enzyme becomes the substrate for the next. In a new finding, researchers report ...

Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a ...
