Architecture of a bacterial power plant decrypted

Both humans and many other creatures need oxygen for survival. In the conversion of nutrients into energy, oxygen is converted to water, for which the enzyme oxidase is responsible. It represents the last step of the so-called ...

Surprising enzymes found in giant ocean viruses

A new study led by researchers at Woods Hole Oceanographic Institution (WHOI) and Swansea University Medical School furthers our knowledge of viruses—in the sea and on land— and their potential to cause life-threatening ...

How a mitochondrial enzyme can trigger cell death

Cytochrome c is a small enzyme that plays an important role in the production of energy by mitochondria. It is also involved in signaling dangerous problems that warrant apoptosis, or programmed cell death. Using solid-state ...

Heat-resistant enzymes could produce more cost-effective drugs

A new study published in Proceedings of the National Academy of Sciences could change the way scientists look at one of the most essential enzymes in medicine in hopes of designing better and more cost-effective drugs in ...

Scientists fill in a piece of the copper transport puzzle

Researchers have identified the protein that carries copper into mitochondria, where copper is required for the functioning of the cell's energy conversion machinery. The discovery, published in the Feb. 9 issue of the Journal ...

Patented bioelectrodes have electrifying taste for waste

New research at Michigan State University and published in the current issue of Nature Communications shows how Geobacter bacteria grow as films on electrodes and generate electricity - a process that's ready to be scaled ...

Discovery suggests possible revolutionary antibiotics

An international team of including the Lomonosov Moscow State University researchers have determined which enzyme enables Escherichia coli bacterium (E. coli) to breathe. The study is published in the Scientific Reports.
