Chain A   (GGTA1_BOVIN | P14769)
molecular function
    GO:0047276    N-acetyllactosaminide 3-alpha-galactosyltransferase activity    Catalysis of the reaction: beta-D-galactosyl-(1,4)-beta-N-acetyl-D-glucosaminyl-R + UDP-galactose = alpha-D-galactosyl-(1,3)-beta-D-galactosyl-(1,4)-beta-N-acetyl-D-glucosaminyl-R + UDP.
    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).
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: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.
