Structure of protein nanoturbine revealed

Cells rely on protein complexes known as ATP synthases or ATPases for their energy needs. Adenosine triphosphate (ATP) molecules power most of the processes sustaining life. Structural biologist Professor Leonid Sazanov and ...

In search of new 'sugar cleavers'

Complex sugars play multiple and essential roles in the living world as structural elements (cellulose), reserve substances (starch), and molecular signals (such as those of blood types), among others. This variety of functions ...

Structure of fat-processing enzyme determined

After decades of work with no success, researchers have determined the high-resolution, three-dimensional structure for lipoprotein lipase, the enzyme that processes fats, or triglycerides, in the bloodstream and releases ...

Glutamine-dependent activation of cell growth discovered

The human body consists of about 35 trillion cells, so it could be said that overall body growth is the growth of individual cells. One essential nutrient for cells are amino acids, the building blocks of proteins (one of ...

Genetic transcription 'pause' is focus of NASA grant

DNA is a blueprint for cells to make proteins that allow those cells to function properly. To create the proteins, enzymes copy genetic codes from DNA strands and then transfer the instructions onto RNA in a process called ...

Fungal enzymes team up to more efficiently break down cellulose

One of the biggest barriers in the commercial production of sustainable biofuels is to cost-effectively break down the bioenergy crops into sugars that can then be converted into fuel. To reduce this barrier, bioenergy researchers ...
