Structural features of FvUGT1. a. Amino acid sequence alignment of FvUGT1 and grapevine VvGT1. Identical and similar amino acids are shaded in black and grey, respectively. The putative calmodulin binding site in FvUGT1 is marked by a red line. The interdomain linker in VvGT1 is marked by a blue line. The conserved putative secondary plant glycosyltransferase (PSPG) motif is underlined with a purple line. b. Homology modeling of FvUGT1 (green) based on the 3D structure of VvGT1 (purple). c. Predicted 3D structure of FvUGT1 showing the regions of the putative calmodulin binding site (red) and the interdomain linker (blue). The overlapping region of the calmodulin-binding site and the interdomain linker is indicated with a purple line. The GenBank accession numbers and sources of proteins are FvUGT1 (KP165417; F. vesca), FaGT1 (AAU09442, F. × ananassa) and VtGT1 (AAB81682; grape)
