    • Provided herein compositions and methods for producing isoprenoids, including squalene. In certain aspects and embodiments provided are genetically altered yeast and uses therefore. In some aspects and embodiments, the genetically altered yeast produce isoprenoids, preferably squalene. The genetically altered yeast may have alterations in the expression or activity of enzymes involved in squalene production, for example, acetyl-CoA carboxylase (or "ACCase"), HMG-CoA reductase, squalene epoxidase, and squalene synthase. One or more genes of a genetically altered yeast may be modified by gene repair oligonucleobases. Also are provided methods of producing squalene using a genetically altered yeast. The invention also provides squalene produced by genetically altered yeast.
    • 提供用于产生类异戊二烯(包括角鲨烯)的组合物和方法。 在某些方面和提供的实施方案是经遗传改变的酵母并因此使用。 在一些方面和实施方案中,遗传改变的酵母产生类异戊二烯,优选角鲨烯。 遗传改变的酵母可能具有改变参与角鲨烯生产的酶的表达或活性,例如乙酰辅酶A羧化酶(或“ACCase”),HMG-CoA还原酶,角鲨烯环氧酶和角鲨烯合酶。 遗传改变的酵母的一个或多个基因可以通过基因修复寡核苷酸修饰。 还提供了使用遗传改变的酵母生产角鲨烯的方法。 本发明还提供由遗传改变的酵母产生的角鲨烯。
