Blood breakdown product commandeers important enzyme

The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, heme is produced, which in turn can influence the protein cocktail in the blood. Researchers ...

Oleandrin is a deadly plant poison, not a COVID-19 cure

With COVID-19 cases and deaths rising in the U.S. and globally, identifying new therapies to prevent and combat the virus is a top priority. Natural products from plants are an attractive option in the search for a cure. ...

Histone H3-H4 tetramer found to be a copper reductase enzyme

A team of researchers at the University of California has found that the histone H3-H4 tetramer is a copper reductase enzyme. In their paper published in the journal Science, the group describes two experiments they carried ...

Algae as living biocatalysts for a green industry

Many substances that we use every day only work in the right 3-D structure. Natural enzymes could produce these in an environmentally friendly way—if they didn't need a co-substrate that is expensive to produce to date. ...

Crumpled graphene makes ultra-sensitive cancer DNA detector

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient's blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it ...
