NMR Structure(hide GO term definitions)
Chain A   (ANPA_PSEAM | P04002)
molecular function
    GO:0050825    ice binding    Interacting selectively and non-covalently with ice, water reduced to the solid state by cold temperature. It is a white or transparent colorless substance, crystalline, brittle, and viscoidal.
biological process
    GO:0042309    homoiothermy    Any homoeostatic process in which an organism maintains its internal body temperature at a relatively constant value. This is achieved by using metabolic processes to counteract fluctuations in the temperature of the environment.
    GO:0050826    response to freezing    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 freezing stimulus, temperatures below 0 degrees Celsius.
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.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
