专利号:US-5350681-A 优先权日:1986-08-18 标题 :Enzymatic membrane method for the synthesis and separation of peptides 发明人:IACOBUCCI GUILLERMO A; BROSE DANIEL J; RAY RODERICK J; VAN EIKEREN PAUL 权利人:COCA COLA CO 摘要:The present invention discloses a method for the enzymatic synthesis of a peptide. A protected peptide having a C-terminal carboxylate group or a protected, N-acyl amino acid having an alpha carboxylate group is reacted with a protected peptide having an N-terminal ammonium group or a protected amino acid having an alpha ammonium group in the presence of a condensation enzyme under conditions in which the carboxylate group and the ammonium group condense to form a protected, uncharged, peptide product. This peptide product is transported across a water-immiscible hydrophobic phase into an aqueous product phase and prevented from back diffusing across the water-immiscible hydrophobic phase. The peptide product can be converted, chemically or enzymatically, to a charged species that cannot back diffuse across the water-immiscible phase into the aqueous reaction phase. The water-immiscible hydrophobic phase is an ion rejection membrane separating the aqueous reaction phase from the product phase creating oil/water interfaces with each of the aqueous phases.

专利号:US-5002871-A 优先权日:1986-08-18 标 题:Enzymatic membrane method for the synthesis and separation of peptides 发明人:IACOBUCCI GUILLERMO A 权利人:COCA COLA CO 摘要:The present invention provides a membrane method for the enzymatic synthesis of peptides accomplished by shifting the chemical equilibrium that exists in a reaction mixture between charged or ionized reacting amino acids and uncharged or non-ionized peptide product in the presence of a proteolytic enzyme such as thermolysin. The equilibrium is shifted by diffusion of the unchanged peptide product across an ion-rejection membrane which removes the uncharged peptide from the reaction mixture and preferably the diffused uncharged peptide is quickly converted to a charged species that cannot back-diffuse into the reaction mixture so that the uncharged peptide is effectively 'pulled' across the membrane. An enzymatic conversion of the uncharged species utilizing an esterase having proteolytic activity such as aminoacylase I is disclosed. Copermeating reactants can be separated from the product mixture and returned to the reaction mixture. Also, the ion-rejection membrane can be utilized to resolve enantiomers of racemic carboxylic acids including D,L-amino acids.
