专利号:US-9255255-B2 优先权日:2013-03-04 标 题 :Synthesis of linear and branched polymers of polypeptides through direct conjugation 发明人:ALBAYRAK CEM; SWARTZ JAMES R; LU YUAN 权利人:UNIV LELAND STANFORD JUNIOR 摘要:Methods are provided for a one step synthesis of polypeptide polymers or co-polymers. The polymers or co-polymers can be linear or branched. In the methods of the invention, the coding sequence for the polypeptide(s) to be polymerized is altered by introducing one or more codons for an nonnatural amino acid, which coding sequence is then utilized to produce the cognate polypeptide. The nonnatural amino acids are selected to be reactive with each other in a bioorthogonal reaction, and are combined in a conjugation reaction with the desired components of the polymer.
