Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial pathogen that is often associated with healthcare settings but can cause serious infections in anyone. These illnesses are difficult ...

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 ...

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 ...

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

A precision-engineered decapeptide reshaping how researchers approach melanogenesis modulation at the enzymatic level.

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 ...

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 ...

WITH our present knowledge of enzyme processes any conception of their mechanism must be essentially highly speculative. In the work under notice the author makes no claim to deal comprehensively with ...

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 ...

The very cells that created us may have a role in saving our lives. Scientists have always been amazed by the energy production system in a sperm’s tail. The system drives flagellar movement and is ...
