Abstract
The present invention provides engineered Saccharomyces eubayanus MalT4 proteins that have maltotriose transport activity. Also provided are polypeptides, constructs, and vectors encoding the engineered MalT4 proteins, as well as S. eubayanus yeast cells that express the engineered MalT4 proteins and methods of using these cells to make a fermentation product, such as a lager.
