Chain A (BFR_PSEAE | Q9HWF9)

molecular function
	GO:0008199	ferric iron binding	Interacting selectively and non-covalently with ferric iron, Fe(III).
	GO:0004322	ferroxidase activity	Catalysis of the reaction: 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.
	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.
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:0006880	intracellular sequestering of iron ion	The process of binding or confining iron ions in an intracellular area such that they are separated from other components of a biological system.
	GO:0006826	iron ion transport	The directed movement of iron (Fe) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	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.
cellular component
	GO:0005623	cell	The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.
