Anapleurosis is the filling of the tricarboxylic acid cycle with four-carbon units. The common substrate for both anapleurosis and glucose phosphorylation in bacteria is the terminal glycolytic ...

The membrane protein complex between the sarcoplasmic reticulum Ca 2+ -ATPase (SERCA) and phospholamban (PLN) controls Ca 2+ transport in cardiomyocytes, thereby modulating cardiac contractility.

The shikimate pathway is fundamental for the biosynthesis of aromatic amino acids—tryptophan, tyrosine and phenylalanine—in plants, bacteria and fungi. This pathway, which is absent in mammals, has ...

Enzymes in multistep metabolic pathways utilize an array of regulatory mechanisms to maintain a delicate homeostasis [K. Magnuson, S. Jackowski, C. O. Rock, J. E. Cronan, Jr, Microbiol. Rev. 57, ...

Sir2, an enzyme belonging to sirtuins, has been effectively involved in the deacetylation of proteins. A tandem allosteric effect of reactant and product is responsible for the efficient deacetylation ...

Yale scientists have taken a novel approach to unraveling the complex structure and regulation of enzymes: They Googled it. In a new study published online this week in the Proceedings of the National ...

The photosynthetic systems of green plants have developed a dual function of efficient light collection under low light intensity and photoprotection under intense sunshine to prevent the oxidative ...

In a recent study posted to the bioRxiv* pre-print server, researchers investigated allosteric binders of angiotensin-converting enzyme 2 (ACE2) that significantly inhibit severe acute respiratory ...

Scientists have created a new way of screening compounds that is more sensitive than existing methods, opening up the possibility of finding new drugs for many diseases. Scientists have created a new ...
