For a number of years, his lab has been experimenting with a synthetic enzyme called diamidophosphate (DAP) that’s been shown to drive a critical chemical process called phosphorylation. Without phosphorylation — which is simply the process of adding a phosphate molecule to another molecule — life wouldn't exist. A method must be developed to detect whether or not the process of phosphorylation is taking place around a star such as KIC 8462852. If the process of how much phosphorylation took place during the very first few millions of years of Earth being in existence can be determined then a map can be created to determine if a solar system is capable of supporting life as well as maintaining life based on the levels of phosphorylation taking place in the solar system.
