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.
