A living cell could be genetically modified to perform a function such as the production of a protein. However, these genetic modifications often conflict with normal cellular function and result in a mutation. Defects can be overcome through removing the bacterial membrane which leaves the lysate that is performing both transcription and translation. The cell free-protein synthesis is also known as in vitro protein synthesis and is the production of a protein without using a living cell. The gene is acting as instructions to make the protein. If we can isolate a gene and then apply a cell free protein synthesis system after synthesis the protein and run on gel-electrophoresis we can identify a gene on the basis of the protein. Gel electrophoresis is a laboratory technique used to ______ contrasting proteins according to molecular size and charge.

ABSTRACT Herewith we report the expression and screening of microbial enzymes without involving cloning procedures. Computationally predicted putative ω-transaminase (ω-TA) genes were PCR amplified from the bacterial colonies and expressed in a cell-free protein synthesis system for subsequent analysis of their enzymatic activity and substrate specificity. Through the cell-free expression analysis of the putative ω-TA genes, a number of enzyme-substrate pairs were identified in a matter of hours. We expect that the proposed strategy will provide a universal platform for bridging the information gap between nucleotide sequence and protein function to accelerate the discovery of novel enzymes.
