| GO term | GO name | GO namespace | GO def |
| GO:0005762 | mitochondrial large ribosomal subunit | cellular_component | The larger of the two subunits of a mitochondrial ribosome. Two sites on the ribosomal large subunit are involved in translation |
| GO:0005759 | mitochondrial matrix | cellular_component | 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. [GOC:as, ISBN:0198506732] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0016740 | transferase activity | molecular_function | 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. [ISBN:0198506732] |
| GO:0008173 | RNA methyltransferase activity | molecular_function | Catalysis of the transfer of a methyl group from a donor to a nucleoside residue in an RNA molecule. [GOC:mah] |
| GO:0003824 | catalytic activity | molecular_function | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

| GO:0019843 | rRNA binding | molecular_function | Binding to a ribosomal RNA. [GOC:jl] |
| GO:0016741 | transferase activity, transferring one-carbon groups | molecular_function | Catalysis of the transfer of a one-carbon group from one compound (donor) to another (acceptor). [GOC:jl, ISBN:0198506732] |
| GO:0008757 | S-adenosylmethionine-dependent methyltransferase activity | molecular_function | Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate. [GOC:mah] |
| GO:0140098 | catalytic activity, acting on RNA | molecular_function | Catalytic activity that acts to modify RNA, driven by ATP hydrolysis. [GOC:molecular_function_refactoring, GOC:pdt] |
| GO:0031167 | rRNA methylation | biological_process | The posttranscriptional addition of methyl groups to specific residues in an rRNA molecule. [GOC:mah] |
| GO:0001510 | RNA methylation | biological_process | Posttranscriptional addition of a methyl group to either a nucleotide or 2'-O ribose in a polyribonucleotide. Usually uses S-adenosylmethionine as a cofactor. [GOC:hjd, PMID:21823225] |
| GO:0008168 | methyltransferase activity | molecular_function | Catalysis of the transfer of a methyl group to an acceptor molecule. [ISBN:0198506732] |
