molecular function
	GO:0047638	albendazole monooxygenase activity	Catalysis of the reaction: albendazole + H(+) + NADPH + O(2) = albendazole S-oxide + H(2)O + NADP(+).
	GO:0070330	aromatase activity	Catalysis of the reduction of an aliphatic ring to yield an aromatic ring.
	GO:0034875	caffeine oxidase activity	Catalysis of the reaction: caffeine + O2 + 2 H+ + 2 e- = 1,3,7-trimethyluric acid + H2O.
	GO:0019899	enzyme binding	Interacting selectively and non-covalently with any enzyme.
	GO:0020037	heme binding	Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.
	GO:0005506	iron ion binding	Interacting selectively and non-covalently with iron (Fe) ions.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0004497	monooxygenase activity	Catalysis of the incorporation of one atom from molecular oxygen into a compound and the reduction of the other atom of oxygen to water.
	GO:0016491	oxidoreductase activity	Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered.
