Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus , and, in plants and algae, the DNA also is ...
MT-ND2 is located in mitochondrial DNA from base pair 4,470 to 5,511. [5] The MT-ND2 gene produces a 39 kDa protein composed of 347 amino acids. [10] [11] MT-ND2 is one of seven mitochondrial genes encoding subunits of the enzyme NADH dehydrogenase (ubiquinone), together with MT-ND1, MT-ND3, MT-ND4, MT-ND4L, MT-ND5, and MT-ND6.
MT-ND3 is located in human mitochondrial DNA from base pair 10,059 to 10,404. [5] The MT-ND3 gene produces a 13 kDa protein composed of 115 amino acids. [9] [10] MT-ND3 is one of seven mitochondrial genes encoding subunits of the enzyme NADH dehydrogenase (ubiquinone), together with MT-ND1, MT-ND2, MT-ND4, MT-ND4L, MT-ND5, and MT-ND6.
In humans, mitochondrial DNA (mtDNA) forms closed circular molecules that contain 16,569 [4] [5] DNA base pairs, [6] with each such molecule normally containing a full set of the mitochondrial genes. Each human mitochondrion contains, on average, approximately 5 such mtDNA molecules, with the quantity ranging between 1 and 15. [ 6 ]
The MT-ND4 gene is located in human mitochondrial DNA from base pair 10,760 to 12,137. [5] [11] The MT-ND4 gene produces a 52 kDa protein composed of 459 amino acids.[12] [13] MT-ND4 is one of seven mitochondrial genes encoding subunits of the enzyme NADH dehydrogenase (ubiquinone), together with MT-ND1, MT-ND2, MT-ND3, MT-ND4L, MT-ND5, and MT-ND6.
MT-ND5 is located in mitochondrial DNA from base pair 12,337 to 14,148. [5] The MT-ND5 gene produces a 67 kDa protein composed of 603 amino acids. [9] [10] MT-ND5 is one of seven mitochondrial genes encoding subunits of the enzyme NADH dehydrogenase (ubiquinone), together with MT-ND1, MT-ND2, MT-ND3, MT-ND4, MT-ND4L, and MT-ND6.
