| molecular function |
|---|
| | GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| | GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| | GO:0008168 | | methyltransferase activity | | Catalysis of the transfer of a methyl group to an acceptor molecule. |
| | GO:0034246 | | mitochondrial RNA polymerase binding promoter specificity activity | | Interacting selectively and non-covalently with a mitochondrial RNA polymerase to form a holoenzyme complex and also, while present in the holoenzyme, interacting with promoter sequences in order to confer sequence specific recognition of mitochondrial promoter DNA sequence motifs. |
| | GO:0000997 | | mitochondrial RNA polymerase core promoter sequence-specific DNA binding | | Interacting selectively and non-covalently with a sequence of DNA that is part of the core promoter for the mitochondrial RNA polymerase. |
| | GO:0000179 | | rRNA (adenine-N6,N6-)-dimethyltransferase activity | | Catalysis of the dimethylation two adjacent A residues in the loop closing the 3'-terminal stem of the 18S rRNA, using S-adenosyl-L-methionine as a methyl donor. |
| | GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
| biological process |
|---|
| | GO:0032259 | | methylation | | The process in which a methyl group is covalently attached to a molecule. |
| | GO:1903108 | | regulation of transcription from mitochondrial promoter | | Any process that modulates the frequency, rate or extent of transcription from mitochondrial promoter. |
| | GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| | GO:0006391 | | transcription initiation from mitochondrial promoter | | A transcription initiation process that takes place at a promoter on the mitochondrial chromosome, and results in RNA synthesis by a mitochondrial RNA polymerase. |
| | GO:0006351 | | transcription, DNA-templated | | The cellular synthesis of RNA on a template of DNA. |
| cellular component |
|---|
| | GO:0034245 | | mitochondrial DNA-directed RNA polymerase complex | | A DNA-directed RNA polymerase complex located in the mitochondrion. Mitochondrial RNA polymerase is composed of two subunits, a catalytic core, which resembles the enzymes from bacteriophage T7 and T3, and a specificity factor required for promoter recognition, which is similar to members of the eubacterial sigma factor family. In S. cerevisiae, these are encoded by the nuclear genes RPO41 and MTF1 and the specificity factor, required for promoter recognition and initiation, is not present in the elongating form. |
| | GO:0005758 | | mitochondrial intermembrane space | | The region between the inner and outer lipid bilayers of the mitochondrial envelope. |
| | GO:0005759 | | mitochondrial matrix | | The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation. |
| | GO:0005739 | | mitochondrion | | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
