An international team of scientists led by researchers at Washington University School of Medicine in St. Louis have found that the enzyme largely responsible for the development of Alzheimer's ...

Telomerase is an enzyme that maintains the DNA at the ends of our chromosomes, known as telomeres. In the absence of telomerase activity, every time our cells divide, our telomeres get shorter. This ...

Subscribe to our newsletter for the latest sci-tech news updates. Proteins that respond to external stimuli function as molecular switches, playing a vital role in the precise regulation of biological ...

A model of the genome is described which relates certain observations on the additive nature of enzyme activity to observations on the quantitative genetics of fitness traits. The model assumes that ...

A naturally occurring human enzyme -called cyclophilin 40 or CyP40- can unravel protein aggregates that contribute to both Alzheimer's disease and Parkinson's disease, according to a study. The ...

Without enzymes, an organism would not be able to survive. It is these biocatalysts that facilitate a whole range of chemical reactions, producing the building blocks of the cells. Enzymes are also ...
