| molecular function |
|---|
| | GO:0051287 | | NAD binding | | Interacting selectively and non-covalently with nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NAD+, or the reduced form, NADH. |
| | GO:0004013 | | adenosylhomocysteinase activity | | Catalysis of the reaction: S-adenosyl-L-homocysteine + H2O = adenosine + L-homocysteine. |
| | GO:0030554 | | adenyl nucleotide binding | | Interacting selectively and non-covalently with adenyl nucleotides, any compound consisting of adenosine esterified with (ortho)phosphate. |
| | GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| | GO:0042802 | | identical protein binding | | Interacting selectively and non-covalently with an identical protein or proteins. |
| | GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| biological process |
|---|
| | GO:0019510 | | S-adenosylhomocysteine catabolic process | | The chemical reactions and pathways resulting in the breakdown of S-adenosylhomocysteine, forming homocysteine and then methionine. |
| | GO:0033353 | | S-adenosylmethionine cycle | | A cyclic series of interconversions involving S-adenosylmethionine, S-adenosyl-L-homocysteine, L-cysteine, and L-methionine. Couples utilization of the methyl group of SAM with recycling of the homocysteinyl group and regeneration of methionine. |
| | GO:0002439 | | chronic inflammatory response to antigenic stimulus | | A chronic inflammatory response to an antigenic stimulus. A chronic inflammatory response persists indefinitely during days, weeks, or months in the life of an individual. |
| | GO:0042745 | | circadian sleep/wake cycle | | The cycle from wakefulness through an orderly succession of sleep states and stages that occurs on an approximately 24 hour rhythm. |
| | GO:0071268 | | homocysteine biosynthetic process | | The chemical reactions and pathways resulting in the formation of homocysteine, 2-amino-4-sulfanylbutanoic acid. |
| | GO:0032259 | | methylation | | The process in which a methyl group is covalently attached to a molecule. |
| | GO:0006730 | | one-carbon metabolic process | | The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states. |
| | GO:0001666 | | response to hypoxia | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. |
| | GO:0007584 | | response to nutrient | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nutrient stimulus. |
| | GO:0000096 | | sulfur amino acid metabolic process | | The chemical reactions and pathways involving amino acids containing sulfur, comprising cysteine, homocysteine, methionine and selenocysteine. |
| cellular component |
|---|
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0070062 | | extracellular exosome | | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. |
| | GO:0042470 | | melanosome | | A tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored. Melanosomes are synthesized in melanocyte cells. |
| | GO:0043005 | | neuron projection | | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| | GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
