Resurrected protein reveals structure of important enzyme

To disarm toxic substances, many organisms including humans possess enzymes called flavin-containing monooxygenases (FMOs). Despite their importance, the structure of the enzymes has not been resolved, as the protein is too ...

Newly discovered protein gives signal for virus infection

Viruses have been part of animals and humans for eons. When viruses invade a cell, they can infiltrate the nucleus with their genome and become part of the genome of the infected organism. Viruses transfer their genes between ...

Scientists now know what DNA's chaperone looks like

It's long been known that the proteins that package DNA, like students at a high school dance, require a chaperone. But what exactly that guardian looks and acts like has been a mystery—until now.

Unraveling gene expression

The DNA of a single cell is two to three meters long end-to-end. To fit in the nucleus and function correctly, DNA is packaged around specialized proteins. These DNA-protein complexes are called nucleosomes, and they are ...
