Abstract
The complete mitochondrial genome of Carcharhinus macloti was determined in this study. It is 16,701 bp in length and contains 37 genes with the typical gene order and transcriptional orientation in vertebrates. A total of 29 bp overlaps and 29 bp short intergenic spaces located in 22 gene junctions. The overall base composition is 31.6% A, 26.2% C, 13.0% G and 29.2% T. Two start codons (ATG and GTG) and three stop codons (AGG, TAG and TAA/T) were found in 13 protein-coding genes. The length of 22 tRNA genes ranged from 66 bp (tRNA-Ser2) to 75 bp (tRNA-Leu1). The tRNA-Ser2 (GCU) lacks the dihydrouridine arm by a simple loop and can not be folded into the typical cloverleaf structure. The control region is 1066 bp in length with high A+T content (68.2%).
