| MELAS | An acronym for mitochondrial myopathy, encephalopathy, lactacidosis, and stroke; an inherited disorder of the respiratory chain, either a deficiency of NADH:ubiquinone oxidoreductase (complex I of the chain) or of cytochrome c oxidase. (05 Mar 2000) |
|---|---|
| melas syndrome | <syndrome> A major subgroup of the mitochondrial encephalomyopathies characterised by mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes. It has been diagnosed in all age groups. (12 Dec 1998) |
| icterus melas | A form in which the skin assumes a dirty dark brown colour. (05 Mar 2000) |
| anti-mitochondrial antibodies | A special serologic test that measures the level of antibodies to a particular portion of a cell (mitochondria). (27 Sep 1997) |
| bovine mitochondrial endonuclease | <enzyme> Dimer of 29kda peptide; prefers a conserved sequence in the displacement loop region of mitochondrial DNA; nicks double-stranded DNA and fragments single-stranded DNA Registry number: EC 3.1.21.- (26 Jun 1999) |
| genome, mitochondrial | The genetic information contained in the circular chromosome of the mitochondrion, a structure located outside the nucleus in the cytoplasm of the cell. The mitochondrial genome and the chromosomal (nuclear) genome together constitute the entire genome. (12 Dec 1998) |
| mitochondrial | Referring to mitochondria. (12 Dec 1998) |
| mitochondrial chromosome | The DNA component of mitochondria, the chief function of which is synthesis of adenosine triphosphate and the management of cellular energy; the chromosome contains some 16,000 base pairs arranged in a circle. The inheritance is matrilineal, and the mutation rate is unusually high; since each cell contains thousands of copies a mutant form may assume an almost continuous gradation as in a galtonian process. Most of the mutations known have their impact on the respiratory chain. (05 Mar 2000) |
| mitochondrial disease | <disease, neurology> An illnesse, frequently neurological, which can be ascribed to defects in mitochondrial function. If the defect is in the mitochondrial rather than the nuclear genome unusual patterns of inheritance can be observed. (18 Nov 1997) |
| mitochondrial encephalomyopathies | Brain diseases associated with disease of the muscles, accompanied by morphological changes in the muscle mitochondria and their metabolism. The mitochondrial encephalopathies are often multisystemic and vary considerably in age at onset, distribution of weakness, severity, and course. Mitochondrial cytochrome c oxidase deficiency appears to be implicated and often several mitochondrial enzymes are affected in the same patient. The brain lesions can be said to be clinical and morphological expressions of a mitochondrial defect. (12 Dec 1998) |
| mitochondrial gene | A functioning gene located not in the nucleus of a cell but in the mitochondrial chromosome. (05 Mar 2000) |
| mitochondrial genome | All of the DNA in the mitochondrial chromosome. (12 Dec 1998) |
| mitochondrial inheritance | The inheritance of a trait encoded in the mitochondrial genome. Because of the oddities of mitochondria, mitochondrial inheritance does not obey the classic rules of genetics. Persons with a mitochondrial disease may be male or female but they are always related in the maternal line and no male with the disease can transmit it to his children. (12 Dec 1998) |
| mitochondrial intermediate peptidase | <enzyme> Removes the octapeptide from the amino terminus of the intermediate protein processed from the protein precursor of certain mitochondrial proteins by the mitochondrial processing peptidase; smip from schizophyllum commune; rmip from rat; ymip from saccharomyces cerevisiae Registry number: EC 3.4.24.59 Synonym: mip peptidase, smip peptidase, rmip peptidase, ymip peptidase (26 Jun 1999) |
| mitochondrial matrix | The substance occupying the space enclosed by the inner membrane of a mitochondrion; it contains enzymes, filaments of DNA, ribosomes, granules, and inclusions of protein crystals, glycogen, and lipid. Synonym: mitochondrial matrix. (05 Mar 2000) |
