Chain A   (P71817_MYCTO | P71817)
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:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    GO:0032934    sterol binding    Interacting selectively and non-covalently with a sterol, any steroid containing a hydroxy group in the 3 position, closely related to cholestan-3-ol.
biological process
    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:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
