Asymmetric Unit(hide GO term definitions)

Chain A,B,C,D (CRVP_PSEAU | Q8AVA4)

molecular function
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
