Fig. 2: Phylogenetic analysis and indole biosynthetic activity of TSB, TSB-like and TSB type II enzymes.
From: A pseudoenzyme enables indole biosynthesis in eudicot plants

a, TSB, TSB-like and TSB type II enzymes form distinct phylogenetic clades. A maximum-likelihood tree was inferred using amino acid sequences. b, Transient expression of AsTSB-like, AsTSB and AsTSB type II in N. benthamiana along with maize Bx2, Bx3, Bx4, Bx5 and Bx8 genes. EIC, extracted ion chromatogram. The chromatogram scale (y axis, peak intensity) is equalized across all chromatograms.
