The purification of a functional soluble protein from biological or in vitro expression systems can be problematic and the enrichment of a functional membrane protein for biochemical analyses can be a serious technical challenge. Recently we have been characterizing plant endomembrane nucleotide sugar transporters using a yeast expression system. However, rather than enriching these in vitro expressed proteins to homogeneity, we have been conducting biochemical characterization of these transport proteins in yeast microsomal fractions. While this approach has enabled us to estimate a variety of kinetic parameters, the accurate determination of the turnover number of an enzyme-substrate compl..View full abstract
