Phylogeny of selected KS domains for selected PKSs in haptophytes generated using Natural Product Domain Seeker (NaPDoS) [22]. Three ketosynthase (KS) domains, one from each species, are more closely related to each other (red), indicating these are likely to be the same module performing the same reaction on one molecule. These are more closely related to another set of KS domains (blue) than any others (not shown) in the genome of these organisms and are more likely to act on the same molecule, as part of a different PKS module. Numbers indicate the contig these KS domains are located on.
