Chain A,B   (MNTR_BACSU | P54512)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0030145    manganese ion binding    Interacting selectively and non-covalently with manganese (Mn) ions.
    GO:0046983    protein dimerization activity    The formation of a protein dimer, a macromolecular structure consists of two noncovalently associated identical or nonidentical subunits.
    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.
    GO:0046914    transition metal ion binding    Interacting selectively and non-covalently with a transition metal ions; a transition metal is an element whose atom has an incomplete d-subshell of extranuclear electrons, or which gives rise to a cation or cations with an incomplete d-subshell. Transition metals often have more than one valency state. Biologically relevant transition metals include vanadium, manganese, iron, copper, cobalt, nickel, molybdenum and silver.
biological process
    GO:0030026    cellular manganese ion homeostasis    Any process involved in the maintenance of an internal steady state of manganese ions at the level of a cell.
    GO:0045893    positive regulation of transcription, DNA-templated    Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    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.
