Fig. 4: A Cellulose synthase-like (Csl) G from S. vaccaria transfers glucuronic acid to C-3 of triterpenoid aglycone quillaic acid.

Kinetic analysis of SvCslG with quillaic acid (a) and UDP-GlcA (b). Error bars indicate mean ± SD (n = 3 biologically independent samples). c Confocal images of SvCslG-YFP transiently coexpressed in N. benthamiana leaves with Golgi-CFP marker and ER-RFP marker. Scale bars, 20 µm. The experiment was repeated in four biologically independent replicates with similar results. Source data are provided as a Source Data file.
