Iron and carbon monoxide are the crucial ingredients that nature uses to process hydrogen, according to researchers. Resolving the structure of the last of the three known hydrogenase enzymes has ...

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

Researchers have uncovered the structure of an enzyme that is crucial for maintaining an adequate supply of deoxyribonucleotides in human cells. Their new structure also reveals the likely mechanism ...

Many microbes have an enzyme that can convert carbon dioxide to carbon monoxide. This reaction is critical for building carbon compounds and generating energy, particularly for bacteria that live in ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

Researchers have determined the atom-by-atom structure of the fermentation enzyme phosphoketolase by cryogenic electron microscopy. They identified details that were mistakenly characterized by X-ray ...

The latest short science news items from C&EN. The team proposes that SAM plays a dual role in the reaction. It donates a methyl group to the enzyme’s cobalamin cofactor and then serves as a base when ...
