Chain A,B   (FKBA_ECOLI | P45523)
molecular function
    GO:0005528    FK506 binding    Interacting selectively and non-covalently with the 23-membered macrolide lactone FK506.
    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: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).
biological process
    GO:0061077    chaperone-mediated protein folding    The process of inhibiting aggregation and assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure that is dependent on interaction with a chaperone.
    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:0042026    protein refolding    The process carried out by a cell that restores the biological activity of an unfolded or misfolded protein, using helper proteins such as chaperones.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    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).
