Cell extract for high-functioned cell-free protein synthesis and method of preparing the extract

摘要

The subjects of the present invention are to prepare a highly functionalized cell extract for cell-free protein synthesis and to specify and eliminate inhibitors and unstable substances present in conventional and various cell extracts for cell-free protein synthesis. Also provided is a method for preparing the cell extract for use in a cell-free protein synthesis means, wherein ATP-mediated phosphorylation pathway of sugar present in the cell extract is controlled. In particular, the control is introducing at least one selected from the following: 1) removing monosaccharides, 2) removing phosphorylated sugars, 3) controlling production of monosaccharides from polysaccharides, and 4) controlling production of phosphorylated sugars from monosaccharides.
