Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (OBP_BOVIN | P07435)
molecular function
    GO:0005549    odorant binding    Interacting selectively and non-covalently with an odorant, any substance capable of stimulating the sense of smell.
    GO:0005215    transporter activity    Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
    GO:0050896    response to stimulus    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism.
    GO:0007608    sensory perception of smell    The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. This is a neurological 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:0005576    extracellular region    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.
