Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Gene Ontology (GO)
7- GO:0009279 A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures.
- GO:0005576 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:0016298 Catalysis of the hydrolysis of a lipid.
- GO:0016042 The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.
- GO:0046819 The process in which proteins mediate their own secretion across the outer membrane through a beta-barrel pore structure formed by the C-terminal domain of the protein precursor. Following passage across the outer membrane, the mature protein is released from the pore by an autocatalytic activity. Proteins secreted by the Type V system are first translocated across the plasma membrane by the Sec pathway.
- GO:0006629 The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.
- GO:0019867 The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites.
