Abstract:
:The entire mitochondrial genome of Rana catesbeiana was cloned into a plasmid vector pBR322 at the unique BamHI site and the nucleotide sequences of the ND2 gene and of its flanking genes were determined. The ND2 gene was encoded by 1,033 base pairs and, as deduced from the nucleotide sequence, the ND2 product consisted of 344 amino acids with a molecular weight of 37,561. This gene was flanked on the 5' side by the tRNA genes for isoleucine, glutamine, and methionine and on the 3' side by those for tryptophan and alanine. These genes were the same in their organization as those found in the mammalian and Xenopus laevis mitochondrial genomes. A comparison of the putative amino acid sequences of the ND2 proteins of different animal species revealed that six regions in the sequence were well conserved during evolution, suggesting that some of these conserved sequences are crucial for biological activity of the ND2 protein. The nucleotide sequence homologies between the five tRNA genes of R. catesbeiana and their counterparts of mammals and X. laevis were in the range of 55 to 85%, depending on the tRNA and animal species.
