Mitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4. [5] Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell.

The matrix contains a highly concentrated mixture of hundreds of enzymes, special mitochondrial ribosomes, tRNA, and several copies of the mitochondrial DNA genome. Of the enzymes, the major functions include oxidation of pyruvate and fatty acids , and the citric acid cycle . [ 20 ]
Mitochondrial DNA is the small circular chromosome found inside mitochondria. These organelles , found in all eukaryotic cells, are the powerhouse of the cell. [ 1 ] The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell .
In mitochondrial matrix, a majority of damaged proteins is removed via proteolysis led by Lon protease, which is an essential mechanism for mitochondrial protein quality control. LONP1 is the major protease responsible for the recognition and removal of unfolded proteins in the mitochondrial matrix and thereby protects the cell from the ...
Mitochondria is a double-membrane structure in the body cell that generates and transports essential metabolic products. The three layers of this structure are the outer membrane, intermembrane space, and inner membrane. [2] The space inside the mitochondria is called the mitochondrial matrix, while the region outside is the cytosol.
ClpP protease is a major contributor for mitochondrial protein quality control system and removing damaged or misfolded proteins in mitochondrial matrix. Defects in mitochondrial Clp proteases have been associated with the progression of neurodegenerative diseases while upregulation of ClpP proteases has been implicated in preventing premature ...
The LYRM7 gene produces a 6.2 kDa protein composed of 53 amino acids, which is a soluble matrix protein with an N-terminal LYR motif. [2] [3] [4] LYRM7 is an assembly factor of the enzyme Ubiquinol Cytochrome c Reductase (UQCR, Complex III or Cytochrome bc1 complex) of the mitochondrial respiratory chain. [1] [5]
