“We have figured out a genetic architecture that allows biomolecular evolution to be very fast.”In addition to speeding and simplifying directed evolution, Liu said this new technique can allow scientists to perform additional types of experiments that they had difficulty doing in the past. %PDF-1.7 The UCI team has eliminated this step entirely in their new approach, letting the cell’s internal machinery do all of the work.According to senior author Chang Liu, UCI assistant professor of biomedical engineering, when using directed evolution to create a better enzyme or protein – the work that won the Nobel Prize in Chemistry this year – the number of evolutionary cycles becomes very important, because each one can be seen as a step toward a new or improved function.

We present automated continuous evolution (ACE), a platform for the hands-free directed evolution of biomolecules. “But if each cycle requires repetitious test-tube DNA molecular biology processing, you can only reasonably go through a few iterations,” he said.“In contrast, natural evolution runs cycles continuously, essentially by culturing cells over time in an environment that pressures them to develop some new function; the problem from a biomolecular engineering standpoint is that the process is very slow,” Liu added. ;����2G옃C��JP�ּiM����V;���m?�\���a������p�A�p5�j��ɸ�G��9b�j2 15 0 obj
