NMR Structure(hide GO term definitions)
Chain A   (SP2AA_BACSU | P10727)
molecular function
    GO:0045152    antisigma factor binding    Interacting selectively and non-covalently with an antisigma factor, a factor which inhibits the ability of the sigma factor to function as a transcriptional initiator.
biological process
    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.
