The wheat germ cell-free protein synthesis is a powerful and versatile method for preparation of proteins based on the accumulated DNA sequence information. As the cell extract used for it contains many factors that are unknown or do not directly involve in protein synthesis, details of the translation reaction is yet to be understood. Therefore, we have decided to try reconstitution of protein synthesis, which would be useful for better understanding of the mechanisms supporting eukaryotic protein synthesis and translational regulation and probably applicable to synthetic biology. In the present study, we fractionated an extract from crude wheat germ according to published protocols to obtain the fractions containing the eukaryotic elongation factors (eEFs) 1A, 1B, and 2. The eEF1A and eEF2 fractions supported polyphenylalanine synthesis.
