Asymmetric Unit(hide GO term definitions)
Chain A   (CRP_ECOLI | P0ACJ8)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0030552    cAMP binding    Interacting selectively and non-covalently with cAMP, the nucleotide cyclic AMP (adenosine 3',5'-cyclophosphate).
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    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:0045013    carbon catabolite repression of transcription    A transcription regulation process in which the presence of one carbon source leads to a decrease in the frequency, rate, or extent of transcription of specific genes involved in the metabolism of other carbon sources. Carbon catabolite repression is a mechanism of genetic regulation which the accumulation of catabolites of one substance in the cell represses the formation of enzymes that contribute to the catabolism of other substances.
    GO:0045892    negative regulation of transcription, DNA-templated    Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
    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:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
