Enzymes accelerate reactions by helping to lower the activation energy needed to start them. But how enzymes achieve this has been the subject of intense debate. A research team from Texas and China ...

The authors’ approach is deceptively simple: take an aldehyde dehydrogenase enzyme, which naturally converts aldehydes to acids, and get it to react with an amine instead of water. But actually making ...

A team of scientists has uncovered a critical mechanism that could pave the way for safer and more effective obesity ...

Researchers from the University of Seville have participated in research to identify the molecular details of the regulation ...

A new study led by scientists at IUPUI and Indiana University Bloomington is the first to describe a biochemical mechanism that increases the activity of a molecule whose presence is observed in many ...

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 ...

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown ...

DALLAS – July 19, 2002 – UT Southwestern Medical Center at Dallas researchers, using X-ray crystallography, have discovered how a particular cell enzyme finds its target and clearly carries out its ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

The enzyme PI3K plays a critical role in cell migration. Scientists have long understood this function. But researchers have recently unveiled that a subunit of this enzyme also has the ability to ...
