Study finds new moves in protein's evolution

Highlighting an important but unexplored area of evolution, scientists at The Scripps Research Institute (TSRI) have found evidence that, over hundreds of millions of years, an essential protein has evolved chiefly by changing ...

Insect gut microbe with a molecular iron reservoir

Microbes are omnipresent on earth. They are found as free-living microorganisms as well as in communities with other higher organisms. Thanks to modern biological techniques we are now able to address the complex communities ...

DNA catalysts do the work of protein enzymes

(Phys.org) —Illinois chemists have used DNA to do a protein's job, creating opportunities for DNA to find work in more areas of biology, chemistry and medicine than ever before.

Positioning enzymes with ease

Virtually all processes in the human body rely on a unique class of proteins known as enzymes. To study them, scientists want to attach these molecules to surfaces and hold them fast, but this can often be a tricky undertaking.

A green transformation for pharmaceuticals

Waste is reduced through the cheap and green development of a catalyst for the transformation of a commercially important functional group

Understanding key enzyme's role in embryonic development

The catalytic activity of an enzyme called Set1A—a protein that is essential to the viability of embryonic stem cells (ESCs)—is not required for ESC self-renewal, according to a Northwestern Medicine study published in ...
