Abstract
Described are strains and methods relating to genetically-engineered yeast cells that overproduce lysine in a tunable manner by altering feedback inhibition of the lysine synthetic pathway by way of the LYS20 and LYS21 homocitrate synthase polypeptides. The yeast can be used in a conventional bioethanol production facility to produce alcohol along with increased amounts of lysine, resulting in increased quality and commercial value of fermentation products and co-products, such as animal feed ingredients.
