An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led ...

CHAPEL HILL – All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these ...

Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the ...

Research has chemists one step closer to recreating nature's most efficient machinery for generating hydrogen gas. This new development may help clear the path for the hydrogen fuel industry to move ...

The economic turmoil unleashed by the Covid-19 pandemic and compounded by the war in Ukraine has resulted in disruption of global supply chains marked by shortages and skyrocketing prices of key raw ...

Saxitoxin—a compound made by marine microbes that can contaminate shellfish—is a toxin so potent that minute quantities can prove deadly. Its mode of action means that less toxic versions have ...

Bacteria love moist surfaces. Once they have settled there, they do not live as solitary organisms but form larger communities that are embedded in a protective film. These biofilms are found on ...

However, conventional chemical synthesis methods have many side reactions and high environmental burdens, and existing ...
