Chain A   (COBT_SALTY | Q05603)
molecular function
    GO:0015420    cobalamin-transporting ATPase activity    Catalysis of the reaction: ATP + H2O + cob(III)alamin(out) = ADP + phosphate + cob(III)alamin(in). Cobalamin is also known as vitamin B12.
    GO:0008939    nicotinate-nucleotide-dimethylbenzimidazole phosphoribosyltransferase activity    Catalysis of the reaction: 5,6-dimethylbenzimidazole + nicotinate D-ribonucleotide = alpha-ribazole 5'-phosphate + H(+) + nicotinate.
    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).
biological process
    GO:0009236    cobalamin biosynthetic process    The chemical reactions and pathways resulting in the formation of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.
    GO:0015889    cobalamin transport    The directed movement of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0009163    nucleoside biosynthetic process    The chemical reactions and pathways resulting in the formation of any one of a family of organic molecules consisting of a purine or pyrimidine base covalently bonded to a sugar ribose (a ribonucleoside) or deoxyribose (a deoxyribonucleoside).
    GO:0035461    vitamin transmembrane transport    The process in which a vitamin is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. A vitamin is one of a number of unrelated organic substances that occur in many foods in small amounts and that are necessary in trace amounts for the normal metabolic functioning of the body.
