Chimeric pufa polyketide synthase system and a method of increasing the production of polyunsaturated fatty acids (pufas) and of altering the omega-3 to omega-6 ratio of pufas produced

摘要

Disclosed are chimeric polyunsaturated fatty acid (PUFA) polyketide synthase (PKS) proteins and chimeric PUFA PKS systems, including chimeric PUFA PKS proteins and systems derived from Schizochytrium and Thraustochytrium. Disclosed are nucleic acids and proteins encoding such chimeric PUFA PKS proteins and systems, genetically modified organisms comprising such chimeric PUFA PKS proteins and systems, and methods of making and using such chimeric PUFA PKS proteins and systems.
