Quantum mechanical calculations reveal the hidden states of enzyme active sites

Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as ‘active’ sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed. Now, researchers have reported the first direct observation of the electronic states of iron-sulfur clusters, common to many enzyme active sites. —> Read More Here
