Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Gene Ontology (GO)
6- GO:0009306 The controlled release of proteins from a cell.
- GO:0015627 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.
- GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
- GO:0015628 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:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
- GO:0046872 Binding to a metal ion.
