Identification and functional characterization of novel plasma membrane carboxylate transporters for biotechnological applications

Several carboxylic acids are among the top value added chemicals produced from biomass, as these building-blocks can be subsequently converted to a number of high-value bio-based chemicals or materials. Different strategies have been developed to improve the cell factory production of these acids; however the export of these molecules is still a major bottleneck. In our group the study of carboxylic acid transporters has been one of the major focuses of research for several years now. The characterization of these transporters is done both at the functional and molecular levels. Transporter proteins are characterized by heterologous expression in a Saccharomyces cerevisiae strain with no carrier-mediated carboxylate transport at the plasma membrane. In addition, structure-function studies are conducted to unravel the mechanisms of substrate recognition and specificity of these proteins. As a final stage, developed metabolic engineered S. cerevisiae robust strains are going to be set growing in bioreator cultivations for otimization of microbial production of desired carboxylic acids.
