Fig. 2From: Evolutionary and functional analysis of mulberry type III polyketide synthasesPhylogenetic analysis of mulberry type III polyketide synthases and other type III polyketide synthases. The indicated scale represents 0.1 amino acid substitutions per site. ALS, aloesone synthase; BBS, bibenzyl synthase; BPS, benzophenone synthase; STCS, stilbenecarboxylate synthase; VPS, valerophenone synthase; OKS, octaketide synthase; 2PS, 2-pyrone synthase; ORS, 2′- oxoalkylresorcinol synthase. The asterisk indicates the branch that is the most recent common ancestor to the plant CHS family. The β-ketoacyl carrier protein synthase III (FABH) of Escherichia coli was used as an outgroupBack to article page
