Role of Elm1, Tos3, and Sak1 Protein Kinases in the Maltose Metabolism of Baker's Yeast.

ABSTRACT: Glucose repression is a key regulatory system controlling the metabolism of non-glucose carbon source in yeast. Glucose represses the utilization of maltose, the most abundant fermentable sugar in lean dough and wort, thereby negatively affecting the fermentation efficiency and product quality of pasta products and beer. In this study, the focus was on the role of three kinases, Elm1, Tos3, and Sak1, in the maltose metabolism of baker's yeast in lean dough. The results suggested that the three kinases played different roles in the regulation of the maltose metabolism of baker's yeast with differential regulations on MAL genes. Elm1 was necessary for the maltose metabolism of baker's yeast in maltose and maltose-glucose, and the overexpression of ELM1 could enhance the maltose
