Chain A (GSPG_PSEAE | Q00514)

molecular function
	GO:0008565	protein transporter activity	Enables the directed movement of proteins into, out of or within a cell, or between cells.
biological process
	GO:0015628	protein secretion by the type II secretion system	The process in which proteins are secreted across the outer membrane of Gram-negative bacteria by the type II secretion system. Proteins using this pathway are first translocated across the cytoplasmic membrane via the Sec or Tat pathways.
	GO:0015031	protein transport	The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
	GO:0015627	type II protein secretion system complex	A large protein complex, containing 12-15 subunits, that spans the cell envelope of Gram-negative bacteria and mediates the movement of proteins into the extracellular environment. The complex includes a component in the cytoplasm, an inner membrane subcomplex that reaches into the periplasmic compartment and a secretion pore in the outer membrane. Proteins using the Type II pathway are transported across the cytoplasmic membrane by the Sec or Tat complex.
