专利号:US-2021002677-A1 优先权日:2015-04-16 标 题:Synthesis of omega functionalized products 发明人:GONZALEZ RAMON; CHEONG SEOKJUNG; CLOMBURG JAMES M 权利人:GONZALEZ RAMON 摘要:The use of microorganisms to make omega- and/or omega-1-functionalized products through an iterative carbon chain elongation pathway that we call a reverse beta oxidation pathway. The pathway uses omega-functionalized CoA thioesters as primers and acetyl-CoA as the extender unit in a non-decarboxylative Claisen condensation, and then uses beta oxidation or fatty acid synthesis enzymes to complete the cycle, via reductase, dehydratase and reductase reactions. Various termination enzymes that act on the functionalized beta-keto acyl-CoA intermediates of the pathway and produce omega or omega-1 functionalized products. The action of termination enzymes on such intermediates yield a large variety of products.

专利号:WO-2016176339-A1 优先权日:2015-04-28 标 题 :Synthesis of omega-phenyl products and derivatives thereof 发明人:GONZALEZ RAMON; CHEONG SEOKJUNG; CLOMBURG JAMES M 权利人:UNIV RICE WILLIAM M 摘要:This disclosure generally relates to the use of microorganisms to make omega-phenyl products, including omega-phenyl carboxylic acids, alcohols, amines, methyl ketones and their beta-functionalized derivatives. This is achieved by utilizing an iterative carbon chain elongation pathway that uses omega-phenyl CoA thioester primers. The core enzymes in the pathway include thiolase, dehydrogenase, dehydratase and reductase. Native or engineered thiolases catalyze the condensation of omega-phenyl CoA thioester primers with acetyl-CoA as the extender unit to generate omega-phenyl β-keto acyl-CoA. Dehydrogenase converts omega-phenyl β-keto acyl-CoA to omega-phenyl β-hydroxy acyl-CoA. Dehydratase converts omega-phenyl β-hydroxy acyl-CoA to omega-phenyl enoyl-CoA. Reductase converts omega- phenyl enoyl-CoA to omega-phenyl acyl-CoA. The platform can be operated in an iterative manner (i.e. multiple turns) by using the resulting omega-phenyl acyl-CoA as primer and acetyl-CoA as extender unit in subsequent turns of the cycle. Termination pathways acting on any of the four omega-phenyl CoA thioester intermediates terminate the platform and generate various omega-phenyl carboxylic acids, alcohols, and amines with different degrees of β -reduction.

This is achieved through an iterative carbon chain elongation pathway that uses omega- functionalized CoA thioesters as primers and acetyl-CoA as the extender unit, in combination with various termination enzymes that act on the omega-functionalized beta-keto acyl-CoA intermediates of the pathway. The action of these termination enzymes on such intermediates yield the aforementioned products.
