Figure 3. Map of the mackerel icefish mitochondrial (mt) genome as a circular diagram. The map represents the mt genome of a type-1 individual in which ND6 and tRNAGlu were transposed to a position between tRNAThr and tRNAPro flanked by intergenic spacers (UN3 and UN4), and the ND6- to -CR segment was duplicated once. Fourteen protein-coding genes, two rRNA genes, and noncoding regions are labelled with abbreviations. Twenty-four tRNA genes are shown by a one-letter amino acid code. Different codons used by each of tRNALeu and tRNASer are shown in parentheses. Genes transcribed from the heavy strand and light strand are respectively presented outside and inside the circle. Heavy- and light-strand replication origins are represented by OH and OL, respectively. Abbreviations: 12S, 12S ribosomal RNA; 16S, 16S ribosomal RNA; A, tRNAAla; ATP, ATP synthase; C, tRNACys; CO, cytochrome oxidase; Cyt b, cytochrome b; D, tRNAAsp; E, tRNAGlu; F, tRNAPhe; G, tRNAGly; H, tRNAHis; I, tRNAIle; K, tRNALys; L, tRNALeu; M, tRNAMet; N, tRNAAsn; ND, nicotiamide adenine dinucleotide (reduced form) dehydrogenase; P, tRNAPro; Q, tRNAGln; R, tRNAArg; S, tRNASer; T, tRNAThr; V, tRNAVal; W, tRNATrp; Y, tRNATyr.
