Genomic architectures of Awi- and Aqu-Spherulin and their evolutionary relationships with homologous prokaryotic sequences. (A) Awi-Spherulin possesses a signal sequence (highlighted grey) indicating it is located extracellularly, within which a 940 bp intron is located. GT/AG splice sites (highlighted red), a polypyrimidine tract (highlighted blue) and putative adenine break point residues (arrows) are indicated. (B) Aqu-Spherulin is located on genome scaffold 13507 (schematically represented here reverse complimented), and is immediately flanked by eukaryotic specific sequences. Scaffold locations are indicated. (C) Bayesian phylogenetic analysis of eukaryotic and prokaryotic Spherulin sequences.
