Asymmetric/Biological Unit(hide GO term definitions)

Chain A (APRA_PSEAE | Q03023)

molecular function
	GO:0005509	calcium ion binding	Interacting selectively and non-covalently with calcium ions (Ca2+).
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0004222	metalloendopeptidase activity	Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.
	GO:0008237	metallopeptidase activity	Catalysis of the hydrolysis of peptide bonds by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.
	GO:0008233	peptidase activity	Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
	GO:0008270	zinc ion binding	Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
	GO:0045959	negative regulation of complement activation, classical pathway	Any process that stops, prevents, or reduces the frequency, rate or extent of complement activation by the classical pathway.
	GO:0001869	negative regulation of complement activation, lectin pathway	Any process that stops, prevents, or reduces the rate of complement activation by the lectin pathway.
	GO:0009405	pathogenesis	The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
	GO:0010765	positive regulation of sodium ion transport	Any process that increases the frequency, rate or extent of the directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0006508	proteolysis	The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
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.
	GO:0005615	extracellular space	That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
