Asymmetric Unit(hide GO term definitions)

Chain A,B,C,D (DPS1_BACAN | Q8RPQ1)

molecular function
	GO:0008199	ferric iron binding	Interacting selectively and non-covalently with ferric iron, Fe(III).
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	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:0016722	oxidoreductase activity, oxidizing metal ions	Catalysis of an oxidation-reduction in which the oxidation state of metal ion is altered.
biological process
	GO:0006879	cellular iron ion homeostasis	Any process involved in the maintenance of an internal steady state of iron ions at the level of a cell.
	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:0006950	response to stress	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation).
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
