PKS phylogenetic tree. The amino acid sequence of the KS domains from 114 fungal and bacterial PKS were used to construct the phylogenetic tree. Numerals on the nodes represent the percentages from 500 bootstraps. Numerals <50 were omitted. Scale: number of substitutions per nucleotide. Colored backgrounds indicate enzyme groups: blue, reducing PKS clades I-IV; orange, non-reducing PKS clades NRI-III and NR bI + II [81]; grey, bacterial PKS; green, fatty acid synthases (FAS)
