Chain A,B,C,D   (SURA_ECOLI | P0ABZ6)
molecular function
    GO:0016853    isomerase activity    Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
    GO:0042277    peptide binding    Interacting selectively and non-covalently with peptides, any of a group of organic compounds comprising two or more amino acids linked by peptide bonds.
    GO:0003755    peptidyl-prolyl cis-trans isomerase activity    Catalysis of the reaction: peptidyl-proline (omega=180) = peptidyl-proline (omega=0).
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0051082    unfolded protein binding    Interacting selectively and non-covalently with an unfolded protein.
biological process
    GO:0043165    Gram-negative-bacterium-type cell outer membrane assembly    The assembly of an outer membrane of the type formed in Gram-negative bacteria. This membrane is enriched in polysaccharide and protein, and the outer leaflet of the membrane contains specific lipopolysaccharide structures.
    GO:0051085    chaperone mediated protein folding requiring cofactor    The process of assisting in the correct posttranslational noncovalent assembly of proteins, which is dependent on additional protein cofactors. This process occurs over one or several cycles of nucleotide hydrolysis-dependent binding and release.
    GO:0060274    maintenance of stationary phase    The homeostatic process in which a population of cells changes its metabolic activity resulting in the rate of death in the population equaling the rate of reproduction. Stationary phase can be in response to limited nutrients or a build-up of toxic substances in the environment.
    GO:0006457    protein folding    The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.
    GO:0000413    protein peptidyl-prolyl isomerization    The modification of a protein by cis-trans isomerization of a proline residue.
    GO:0050821    protein stabilization    Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.
    GO:0044010    single-species biofilm formation    A process in which planktonically growing microorganisms of the same species grow at a liquid-air interface or on a solid substrate under the flow of a liquid and produce extracellular polymers that facilitate matrix formation, resulting in a change in the organisms' growth rate and gene transcription.
cellular component
    GO:0030288    outer membrane-bounded periplasmic space    The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
    GO:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
