| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | 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:0016757 | | transferase activity, transferring glycosyl groups | | Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor). |
| | GO:0016758 | | transferase activity, transferring hexosyl groups | | Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor). |

| | 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:0033580 | | protein galactosylation at cell surface | | The addition of a galactose unit to a protein amino acid at the surface of a cell. |
| | GO:0006486 | | protein glycosylation | | A protein modification process that results in the addition of a carbohydrate or carbohydrate derivative unit to a protein amino acid, e.g. the addition of glycan chains to proteins. |
| 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:0031985 | | Golgi cisterna | | Any of the thin, flattened membrane-bounded compartments that form the central portion of the Golgi complex. |
| | GO:0032580 | | Golgi cisterna membrane | | The lipid bilayer surrounding any of the thin, flattened compartments that form the central portion of the Golgi complex. |
| | GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
