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 ...

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 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 ...

A group of researchers have expanded conventional knowledge on a critical enzyme that controls cell migration. In a publication in the journal Nature Communications, they reported that ...

The polysaccharide β-1,2-glucan consists of repeating units of glucose linked together by β-1,2-glycosidic bonds. Cyclic β-1,2-glucans (CβGs) occur in different bacterial species and have a role in ...

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 ...

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 ...

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

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 ...

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 ...
