Residue interactions as predicted by UGT76G1 homology modelling. a π-stacking between Phe18 and Trp127 b Hydrogen bond formation from Asp380 to Asn151, Lys191, Asn384 and to a Reb M glucose moiety. c Hydrogen bond formation from His155 with Reb M and the Leu379 directing planar conformation of the glucose residues of the stevioside. d Hydrogen formation from Ser283 to the C 13-glucose moieties
