Relationships among paralytic shellfish toxin (PST) production, protein translation and chlorophyll biosynthesis. Dark circles represent the proteins identified in this study. The dashed box on top shows the putative PST biosynthesis pathway in dinoflagellates (modified from previous reports [4,9,32]), and the dashed box on the bottom summarizes the route of chlorophyll biosynthesis (modified from previous reports [33,34]). The abbreviations are: TCA: tricarboxylic acid cycle; gltX: glutamyl-tRNA synthetase; chlI: magnesium chelatase subunit I; por: protochlorophyllide reductase; hemL: oxygen-dependent protoporphyrinogen oxidase; argJ: glutamate N-acetyltransferase/amino acid N-acetyltransferase; GLT1: glutamate synthase (NADH).
