Complete mitochondrial DNA genome of Metzia mesembrinum (Cypriniformes: Cyprinidae)

In this study, we sequenced the complete mitochondrial genome of Metzia mesembrinum (Cypriniformes, Cyprinidae), an Endangered pelagic primary freshwater fish distributed in South China. This mitochondrial genome, consisting of 16,611 base pairs (bp), encoded 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a noncoding control region as those found in other vertebrates, with the gene synteny identical to that of typical vertebrates. Control region (D-Loop), of 936bp long, was located between tRNA(Pro) and tRNA(Phe). The overall base composition of the heavy strand shows T 26.83%, C 25.48%, A 32.01% and G 15.68%, with a slight AT bias of 58.84%.
