Fig. 2.

An unusual, very large NRPS-PKS protein is present in the Symbiodinium minutum genome. a Consensus schematic representation of the NRPS-PKS hybrid from S. minutum based on the PFAM database and anti-SMASH. Acyl carrier protein (ACP) is represented as phosphopantetheine (PP). The third A domain didn’t yield any prediction for a specific substrate using anti-SMASH. Amino acid (aa) positions show starting points for major domains. AT: acyl tansferase, C: condensation, A: adenylation, KS: ketosynthase, DH: dehydratase, KR: ketoreductase, MT: methyltransferase, TE: thioesterase b core scaffold of the hypothetical molecule, based on assumed PKS-NRPS co-linearity
