Production of polyunsaturated fatty acids (PUFAs) using a novel modular docosahexaenoic acid (DHA) synthase

This disclosure concerns a novel modular docosahexaenoic acid (DHA) synthase and recombinant host organisms genetically modified with such synthase and one or more accessory proteins that allow for and/or improve the production of PUFAs in the host organism. The disclosure also concerns methods of making and using such organisms as well as products obtained from such organisms.
