UCSF team develops 'logic gates' to program bacteria as computers
Date:12/8/2010

omedical advances," said Koda-Kimble, who championed Voigt's recruitment to lead this field at UCSF in 2003. "It's an amazing and exciting relationship to watch cellular systems and synthetic biology unfold before our eyes."

The Nature paper describes how the Voigt team built simple logic gates out of genes and inserted them into separate E. coli strains. The gate controls the release and sensing of a chemical signal, which allows the gates to be connected among bacteria much the way electrical gates would be on a circuit board.

"The purpose of programming cells is not to have them overtake electronic computers," explained Voigt, whom Scientist magazine named a "scientist to watch" in 2007 and whose work is included among the Scientist's Top 10 Innovations of 2009. "Rather, it is to be able to access all of the things that biology can do in a reliable, programmable way."

The research already has formed the basis of an industry partnership with Life Technologies, in Carlsbad, Cal., in which the genetic circuits and design algorithms developed at UCSF will be integrated into a professional software package as a tool for genetic engineers, much as computer-aided design is used in architecture and the development of advanced computer chips.

The automation of these complex operations and design choices will advance basic and applied research in synthetic biology. In the future, Voigt said the goal is to be able to program cells using a formal language that is similar to the programming languages currently used to write computer code.
