Figure 2From: Cloning and characterization of a glucosyltransferase from Crocus sativusstigmas involved in flavonoid glucosylationAmino acids sequence alignment of CsGT45 against MtUGT71G1 and structures comparison. (A) The alignment was performed guided by conservation of secondary structure, predicted for CsGT45 (B9UYP6) and observed from the solved crystal structure of MtUGT71G1 (Q5IFH7). α-helices are highlighted in blue and β-strands in pink. Structurally conserved regions (SCRs) are highlighted by dots above the alignment. Loops are numbered and named above the alignment. The amino acids residues within the PSPG motif that interact in MtUGT71G1 with the sugar donor are marked with starts. (B) Ribbon diagrams showing the conserved secondary and tertiary structure of MtUGT71G1 (right) used as template for modelling of CsGT45 and the constructed model (left).Back to article page
