Biochemical characterization of CsGT1 and At_UGT85As. A, CsGT1 catalyzes the glucosylation of geraniol to produce geranyl-glc. B, LC-MS analysis of the enzymatic product of CsGT1 (UGT85K11) and At_UGT85A3 (At1g22380) compared with the authentic standard (geranyl-glu). n.d., Not detected; r.t., retention time; SIM, selected ion monitoring. C, Relative activity of CsGT1 toward sugar acceptors [geraniol, linalool, eugenol, benzyl alcohol, (Z)-3-hexenol, 2-PE, quercetin, and cyanidin]. D, Relative activity of CsGT1 toward sugar donors (UDP-Glc, UDP-Xyl, UDP-Gal, and UDP-GlcA). Data are presented as means ± sd (n = 3).
