molecular function |
| GO:0004557 | | alpha-galactosidase activity | | Catalysis of the hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha-D-galactosides, including galactose oligosaccharides, galactomannans and galactohydrolase. |
| GO:0003824 | | 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:0016936 | | galactoside binding | | Interacting selectively and non-covalently with any glycoside in which the sugar group is galactose. |
| 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:0016798 | | hydrolase activity, acting on glycosyl bonds | | Catalysis of the hydrolysis of any glycosyl bond. |
| GO:0004553 | | hydrolase activity, hydrolyzing O-glycosyl compounds | | Catalysis of the hydrolysis of any O-glycosyl bond. |
| 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). |
| GO:0042803 | | protein homodimerization activity | | Interacting selectively and non-covalently with an identical protein to form a homodimer. |
| GO:0052692 | | raffinose alpha-galactosidase activity | | Catalysis of the reaction: raffinose + H2O = alpha-D-galactose + sucrose. |
| GO:0005102 | | receptor binding | | Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. |
biological process |
| GO:0005975 | | carbohydrate metabolic process | | The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule. |
| GO:0046479 | | glycosphingolipid catabolic process | | The chemical reactions and pathways resulting in the breakdown of glycosphingolipid, a compound with residues of sphingoid and at least one monosaccharide. |
| GO:0006687 | | glycosphingolipid metabolic process | | The chemical reactions and pathways involving glycosphingolipids, any compound with residues of sphingoid and at least one monosaccharide. |
| GO:0046477 | | glycosylceramide catabolic process | | The chemical reactions and pathways resulting in the breakdown of glycosylceramides, any compound formed by the replacement of the glycosidic hydroxyl group of a cyclic form of a monosaccharide (or derivative) by a ceramide group. |
| 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:0045019 | | negative regulation of nitric oxide biosynthetic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of nitric oxide. |
| GO:0051001 | | negative regulation of nitric-oxide synthase activity | | Any process that stops or reduces the activity of the enzyme nitric-oxide synthase. |
| GO:0009311 | | oligosaccharide metabolic process | | The chemical reactions and pathways involving oligosaccharides, molecules with between two and (about) 20 monosaccharide residues connected by glycosidic linkages. |
cellular component |
| GO:0005794 | | Golgi apparatus | | A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| 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:0005576 | | extracellular region | | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. |
| GO:0043202 | | lysosomal lumen | | The volume enclosed within the lysosomal membrane. |
| GO:0005764 | | lysosome | | A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions. |
