In order to improve the performance of in vitro protein synthesis reactions, metabolic inhibitors, or manipulation of a source organism, is used to diminish or avoid the action of enzymes responsible for undesirable amino acids production or depletion. A homeostatic system may be used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.

In part, the invention is a recognition and appreciation that different TdT variants can be engineered to preferentially incorporate specific dNTPs with higher efficiency than a single “general purposeâ€? TdT variant used to incorporate all four 3-O-reversibly blocked dNTPs.
专利号:WO-9720061-A1 优先权日:1995-11-30 标题:Synthesis of hyaluronic acid 发明人:WONG CHI-HUEY; DELUCA CLAUDIO 权利人:SCRIPPS RESEARCH INST; WONG CHI HUEY; DELUCA CLAUDIO 摘要:A preparative enzymatic synthesis of hyaluronic acid (HA) from UDP-N-acetyl-D-glucosamine (UDP-GlcNAc) and UDP-glucuronic acid (UDP-GlcA) catalyzed by hyaluronic acid synthase is coupled with regeneration of the sugar nucleotides. Polymerizing UDP-GlcA and UDP-GlcNAc to form hyaluronic acid results in the formation of released UDP. The released UDP is, in turn, employed in the regeneration of UDP-GlcA and UDP-GlcNAc. Use of the released UDP for regenerating UDP-GlcA and UDP-GlcNAc prevents a build-up of these compounds and prevents or reduces feed back inhibition of the hyaluronic acid synthase reaction that would otherwise be caused by such build-up. Accordingly, the product yield is enhanced by the recycling of these compounds.
