The nucleotide sequence of a 9240-base pair DNA fragment of the mitochondrial (mt) genome of a squid, Loligo bleekeri, was determined, in which 8 protein and 14 tRNA genes were identified. The gene organization of the mt-genome exhibits a greater resemblance to the gene organization of arthropods and a chiton, Katharina tunicata, than to those of a mussel, Mytilus edulis, and land snails. A cloverleaf-like structure was observed between the genes for subunits 4 and 5 of NADH dehydrogenase (ND4 and -5), which is considered to have originated from histidine tRNA. It is presumed that this structure functions as a transcriptional punctuation signal for the maturation of the ND4 and ND5 mRNAs.
