  • Method for increasing the ratio of p-hydroxybenzoic acid ester glucoside to total p-hydroxybenzoic acid glucose conjugates in p-hydroxybenzoic acid-producing microorganisms and green plant cells
    Patent number: 7435556
    Abstract: This invention pertains to a method for increasing the ratio of the pHBA ester glucoside to total pHBA glucose conjugates in pHBA-producing microorganisms and green plant cells using nucleic acid fragments encoding plant glucosyltransferases that exhibit catalytic activity with p-hydroxybenzoic acid (pHBA) as a substrate and only attach glucose to the aromatic carboxyl group of pHBA, to form the pHBA glucose ester.

  • UDP-glucosyltransferases
    Publication number: 20060177905
    Abstract: This invention pertains to nucleic acid fragments encoding plant glucosyltransferases, heretofore undescribed, that exhibit catalytic activity with p-hydroxybenzoic acid (pHBA) as a substrate and only attach glucose to the aromatic carboxyl group of pHBA, to form the pHBA glucose ester. These enzymes have potential applications both in vitro and in vivo, and their primary amino acid sequences can be used to identify other proteins that have similar kinetic properties.
