Aphrocallistes vastus mtDNA. The mitochondrial genome of the hexactinellid Aphrocallistes vastus was determined to be a 17,427 bp circular molecule encoding 13 respiratory genes, two ribosomal RNAs and 18 tRNAs. Protein coding genes are represented in green, ribosomal RNAs in blue, and tRNAs with black boxes. The 411 bp unknown open reading frame (orf411) is shown in yellow, and a 568 bp intergenic space (is568) – a putative control region – is in red. Transfer RNAs are labeled with their one letter IUPAC amino acid abbreviation. All genes are encoded on the same strand.
