A resurrected ancient enzyme is helping scientists test how reliably Earth’s oldest rocks record signs of life.

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 ...

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 ...

Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

A UCSF team finds a liver protein, released with exercise, that improves memory in aging and Alzheimer’s disease by repairing the brain’s blood vessels. It's the missing link between exercise and ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

Researchers identified more than 200 metabolic enzymes attached to human DNA, forming unique nuclear metabolic fingerprints across tissues and cancers.

Researchers have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The discovery, which may be important for research into developing ...

Researchers have found evidence of nuclear metabolic enzymes for the first time, contributing to our understanding of cancer ...
