'Shark molecule' protects cholesterol enzyme from destruction

A team of scientists have shown in cell lines that a key cholesterol synthesis enzyme—squalene monooxygenase (SM) – is controlled by the levels of its target molecule, squalene. The findings, published in international ...

Insight into enzyme's 3-D structure could cut biofuel costs

Using neutron crystallography, a Los Alamos research team has mapped the three-dimensional structure of a protein that breaks down polysaccharides, such as the fibrous cellulose of grasses and woody plants, a finding that ...
