Chain A,B (MOEA_ECOLI | P12281)

molecular function
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0061598	molybdopterin adenylyltransferase activity	Catalysis of the reaction ATP + molybdopterin = diphosphate + adenylyl-molybdopterin.
	GO:0061599	molybdopterin molybdotransferase activity	Catalysis of the reaction adenylyl-molybdopterin + molybdate = molybdenum cofactor + AMP.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	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.
biological process
	GO:0006777	Mo-molybdopterin cofactor biosynthetic process	The chemical reactions and pathways resulting in the formation of the Mo-molybdopterin cofactor, essential for the catalytic activity of some enzymes. The cofactor consists of a mononuclear molybdenum (Mo) ion coordinated by one or two molybdopterin ligands.
	GO:0018315	molybdenum incorporation into molybdenum-molybdopterin complex	The incorporation of molybdenum into a molybdenum-molybdopterin complex.
	GO:0032324	molybdopterin cofactor biosynthetic process	The chemical reactions and pathways resulting in the formation of the molybdopterin cofactor (Moco), essential for the catalytic activity of some enzymes, e.g. sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase. The cofactor consists of a mononuclear molybdenum (Mo-molybdopterin) or tungsten ion (W-molybdopterin) coordinated by one or two molybdopterin ligands.
cellular component
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
