Flavonoids are plant secondary metabolites well known for many key roles in the life cycle of plants. They also can affect human health. Citrus paradisi is known to produce several glucosylated flavonoids and these compounds are glucosylated by enzymes known as glucosyltransferases (GTs). The focus of this research was to optimize the heterologous expression, enrichment, and biochemical characterization of grapefruit putative GT protein, PGT2, and to test the hypothesis that PGT2 is a flavonoid GT. Results showed detectable amounts of activity with quercetin, a flavonol; however, activity was lower than what would be expected if this enzyme were a flavonol-specific GT. In an additional aspect of this study, bioinformatics were used to test the hypothesis that additional putative GT clones could be identified using the harvEST database.
