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 ...

Microorganisms build the best fuel efficient hydrogen cells

For all the advances technology has made throughout our lives, in many cases it stands behind what nature can do. Ants can carry 5000 times their weight, and spider webs are five times stronger than steel. Fuel efficiency ...

Single-atom nanozymes

Nanozymes are catalytic nanomaterials with enzyme-like characteristics that have attracted enormous recent research interest. The catalytic nanomaterials offer unique advantages of low cost, high stability, tunable catalytic ...

Paper sensors remove the sting of diabetic testing

A technique that enables biologically active enzymes to survive the rigors of inkjet printing presents a promising alternative to routine blood screening finger jabs for diabetic blood sugar levels. The KAUST-led team used ...

Bioinspired enzyme model with a redox switch

Coupled oxygen transfer and electron transfer reactions that use cofactors are enzymatic reactions of crucial significance to all lifeforms from bacteria to vertebrates. In the European Journal of Inorganic Chemistry, scientists ...

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 ...

Formation of the browning pigment melanin decoded

Melanin is a pigment which is present in almost all life forms and that determines hair and skin color in humans. It helps insects protect themselves against the effects of pathogenic microorganisms and it promotes tissue ...
