The brain needs its surroundings to be just right. That is, unlike some internal organs, such as the liver, which can process just about anything that comes its way, the brain needs to be protected and to have a chemical environment with the right balance of proteins, sugars, salts, and other metabolites.

Protein engineers at Caltech have tapped into a hidden talent of one of nature's most versatile catalysts. The enzyme cytochrome P450 is nature's premier oxidation catalyst—a protein that typically promotes reactions that add oxygen atoms to other chemicals. Now the Caltech researchers have engineered new versions of the enzyme, unlocking its ability to drive a completely different and synthetically useful reaction that does not take place in nature.

Chemists at Caltech have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes. The feat required bridging timescales from the realm of nanoseconds all the way up to full minutes, exceeding the scope of earlier simulation efforts by more than six orders of magnitude. The result is a detailed molecular understanding of how the translocon works.
