GO:0008250 | oligosaccharyltransferase complex | cellular_component | A protein complex that is found in the endoplasmic reticulum membrane of eukaryotes and transfers lipid-linked oligosaccharide precursor to asparagine residues on nascent proteins. In yeast, the complex includes at least nine different subunits, whereas in mammalian cells at least three different forms of the complex have been detected. [ISBN:0879695595, PMID:15835887] |
GO:0016020 | membrane | cellular_component | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |

GO:0006486 | protein glycosylation | biological_process | 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. [GOC:curators, GOC:pr] |
GO:0005783 | endoplasmic reticulum | cellular_component | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). [ISBN:0198506732] |

GO:0050790 | regulation of catalytic activity | biological_process | Any process that modulates the activity of an enzyme. [GOC:ai, GOC:ebc, GOC:vw] |
GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
GO:0043231 | intracellular membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. [GOC:go_curators] |
GO:0030659 | cytoplasmic vesicle membrane | cellular_component | The lipid bilayer surrounding a cytoplasmic vesicle. [GOC:mah] |
GO:0016021 | integral component of membrane | cellular_component | 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. [GOC:dos, GOC:go_curators] |
GO:0030667 | secretory granule membrane | cellular_component | The lipid bilayer surrounding a secretory granule. [GOC:mah] |
GO:0031090 | organelle membrane | cellular_component | A membrane that is one of the two lipid bilayers of an organelle envelope or the outermost membrane of single membrane bound organelle. [GOC:dos, GOC:mah] |
GO:0018279 | protein N-linked glycosylation via asparagine | biological_process | The glycosylation of protein via the N4 atom of peptidyl-asparagine forming N4-glycosyl-L-asparagine; the most common form is N-acetylglucosaminyl asparagine; N-acetylgalactosaminyl asparagine and N4 glucosyl asparagine also occur. This modification typically occurs in extracellular peptides with an N-X-(ST) motif. Partial modification has been observed to occur with cysteine, rather than serine or threonine, in the third position; secondary structure features are important, and proline in the second or fourth positions inhibits modification.
