A Helices are numbered H in ascending order and sheets of the N- and C-terminal domains are numbered A and B, respectively. The β and γ designations stand for beta and gamma turns, respectively and contacts of residues to ligands are indicated by a small red box. Generated by PDBsum (https://www.ebi.ac.uk/thornton-srv/databases/pdbsum/Generate.html). A green, red and blue bar indicates the plant secondary product glycosyltransferase (PSPG) motif, the unordered/helix transition region and the closing loop segment, respectively. A black arrow marks catalytically active His18 and Trp350. B Representation of the B-factors (in Å2) as specified in PDB 9J9K.
