Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (PYP_HALHA | P16113)
molecular function
    GO:0009881    photoreceptor activity    The function of absorbing and responding to incidental electromagnetic radiation, particularly visible light. The response may involve a change in conformation.
biological process
    GO:0007602    phototransduction    The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.
    GO:0018298    protein-chromophore linkage    The covalent or noncovalent attachment of a chromophore to a protein.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    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.
