|
catalytic activity
|
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:0008152
|
metabolic process
|
The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |

|
GO:0044237
|
cellular metabolic process

|
histone-lysine N-methyltransferase activity
|
Catalysis of the reaction: S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N6-methyl-L-lysine. The methylation of peptidyl-lysine in histones forms N6-methyl-L-lysine, N6,N6-dimethyl-L-lysine and N6,N6,N6-trimethyl-L-lysine derivatives. |

GO:0031151
|
histone methyltransferase activity (H3-K79 specific)
|
Catalysis of the reaction: S-adenosyl-L-methionine + histone H3 L-lysine (position 79) = S-adenosyl-L-homocysteine + histone H3 N6-methyl-L-lysine (position 79). This reaction is the addition of a methyl group onto lysine at position 79 of the histone H3 protein. |
|
GO:0034729
|
histone H3-K79 methylation
|
The modification of histone H3 by addition of a methyl group to lysine at position 79 of the histone. |

Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate. |
|
GO:0019538
|
protein metabolic process
|
The chemical reactions and pathways involving a specific protein, rather than of proteins in general. Includes protein modification. |
|
GO:0051276
|
chromosome organization
|
A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. This term covers covalent modifications at the molecular level as well as spatial relationships among the major components of a chromosome. |
|
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. |
|
GO:0016568
|
chromatin modification
|
The alteration of DNA, protein, or sometimes RNA, in chromatin, which may result in changing the chromatin structure. |
|
GO:0006464
|
cellular protein modification process
|
The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications) occurring at the level of an individual cell. Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). |
|
GO:0071704
|
organic substance metabolic process
|
The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon. |
|
GO:0006479
|
protein methylation
|
The addition of a methyl group to a protein amino acid. A methyl group is derived from methane by the removal of a hydrogen atom. |
|

|
GO:0043412

|
The covalent alteration of one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule, resulting in a change in its properties. |
|
GO:0032259
|
methylation
|
The process in which a methyl group is covalently attached to a molecule. |
|
GO:0044238
|
primary metabolic process
|
The chemical reactions and pathways involving those compounds which are formed as a part of the normal anabolic and catabolic processes. These processes take place in most, if not all, cells of the organism. |
|
GO:0008276
|
