Asymmetric Unit(hide GO term definitions)

Chain A (URIC_ASPFL | Q00511)

molecular function
	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. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
	GO:0004846	urate oxidase activity	Catalysis of the reaction: urate + O2 + H2O = 5-hydroxyisourate + hydrogen peroxide.
biological process
	GO:0055114	oxidation-reduction process	A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
	GO:0006144	purine nucleobase metabolic process	The chemical reactions and pathways involving purine nucleobases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine.
	GO:0019628	urate catabolic process	The chemical reactions and pathways resulting in the breakdown of urate, the anion of uric acid, 2,6,8-trioxypurine.
cellular component
	GO:0005777	peroxisome	A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism.
