Synthetic enzymes may be catalysts for artificial life

A recent study from the Princeton team has brought a big step for the future by asserting that an artificial protein developed by this team could work as an enzyme in living bacteria.

Over the years, Princeton made artificial proteins for E. coli that is a kind of unaffected bacteria commonly used as a clinical trial in medicine. To test the possibility of research, they eliminated some types of gen that could lead to bacteria being unable to produce the Fes enzyme, which cells use to obtain iron. Without that vital mineral, bacteria would not have survived, but the team then implanted artificial proteins that could replace lost functions optimism to “save a life” or revive bacteria.

In this new research team, the researchers confirmed the way which new protein works. They found that two of them saved E. coli by offsetting lost enzymes, which could promote the production of other processes in the cell. 

 “This artificial protein, scientifically named Syn-F4, is an enzyme”, the primary researcher- Mr. Ann Donnelly said

An artificial enzyme likes Syn-F4 is an important step to develop synthetic biology experiments. Not only can these life forms be designed to effectively build food, fuel, and medicine, but they can also help us understand how life can arise in other situations – for example, on other planets …

“We have liberated 0.1% of the E. coli genome. So far, it is an uncanny E. coli containing some artificial genes that allow bacteria to grow easily,” said Hecht. Moreover, the experts hypothesized that if the amount of artificial enzyme for replacement is up to the rate of 10-20% working successfully, this E. coli is no longer strange, and it becomes a new organism.

This research has been declared in Nature Chemical Biology magazine.
