Fig. 5: Motifs and amino acid mutations of proteins related to the CSOs biosynthesis.

a Schematic representation of the motifs for the LFS. b Specific mutations located in the binding pockets of alliinase and LFS. A comparison of the sequence logos of Allium species (633 sequences of alliinase and 515 of LFS) and non-Allium species (48 sequences of alliinase and 53 of LFS) is shown. c 3D structural models and LigPlot+ diagrams for alliinase/alliin. d 3D models and LigPlot+ diagrams for LFS/(E)-1-propene−1-sulfenic acid (1-PSA). The amino sites in the binding pockets are shown in light blue, substrates are shown in yellow, and PLP cofactors are shown in pink in the 3D models. Hydrogen bonds are displayed as green dashed lines, while hydrophobic (or non-bonded) interactions are displayed as red opposite arcs in LigPlot+ diagrams. Source data underlying panels (a) and (b) are provided as Source Data file.
