权利人:UNIV LELAND STANFORD JUNIOR
摘要:Methods, microbial strains and reaction mixtures for cell-free synthesis of polypeptides are provided. The methods of the invention utilize a reaction mixture comprising microbial cell extracts that are modified in the protein component relative to an extract from a native cell. The modification may be one or both of (i) increased levels of proteins that increase synthetic yield; and (ii) decreased levels of proteins that decrease synthetic yield. The modification may result from a genetic modification of the microbial cell, or from ex vivo supplementation or depletion of an extract.
