Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B,C   (SP0A_GEOSE | P52934)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0003700    transcription factor activity, sequence-specific DNA binding    Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
biological process
    GO:0051606    detection of stimulus    The series of events in which a stimulus is received by a cell or organism and converted into a molecular signal.
    GO:0000160    phosphorelay signal transduction system    A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins.
    GO:0043937    regulation of sporulation    Any process that modulates the frequency, rate or extent of sporulation, the process whose specific outcome is the progression of a spore over time, from its initiation to the mature structure.
    GO:0042173    regulation of sporulation resulting in formation of a cellular spore    Any process that modulates the frequency, rate or extent of spore formation.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0030435    sporulation resulting in formation of a cellular spore    The process in which a relatively unspecialized cell acquires the specialized features of a cellular spore, a cell form that can be used for dissemination, for survival of adverse conditions because of its heat and dessication resistance, and/or for reproduction.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
