Figure 2. Phylogenetic tree of Type I and Type II KS domains from prokaryotic and eukaryotic PKS and FAS.

Figure 2

Fifty-nine taxa representing Type I and Type II KS domains were analyzed by a maximum likelihood approach. The Type II KS and the acyl carrier protein synthases (ACPS) were used as outgroup. Approximate likelihood ratios ≥50% and bootstrap values ≥50% are marked on appropriate branches like (50/50). A. Overall tree topology is in accord with previous reports [5], [10]. Dinoflagellate KS is classified as a well supported group within the protistan Type I FAS/PKS clade. B. Within the dinoflagellate KS group, one clade containing sequences from different species and one only from K. brevis can be observed.
