Chain A,B,C,D,E,F   (PUTA_ECOLI | P09546)
molecular function
    GO:0003842    1-pyrroline-5-carboxylate dehydrogenase activity    Catalysis of the reaction: 1-pyrroline-5-carboxylate + NAD+ + H2O = L-glutamate + NADH + H(+).
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0004029    aldehyde dehydrogenase (NAD) activity    Catalysis of the reaction: an aldehyde + NAD+ + H2O = an acid + NADH + H+.
    GO:0000986    bacterial-type RNA polymerase core promoter proximal region sequence-specific DNA binding    Interacting selectively and non-covalently with a sequence of DNA that is in cis with and relatively close to a core promoter for a bacterial-type RNA polymerase.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0050660    flavin adenine dinucleotide binding    Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0016620    oxidoreductase activity, acting on the aldehyde or oxo group of donors, NAD or NADP as acceptor    Catalysis of an oxidation-reduction (redox) reaction in which an aldehyde or ketone (oxo) group acts as a hydrogen or electron donor and reduces NAD or NADP.
    GO:0004657    proline dehydrogenase activity    Catalysis of the reaction: L-proline + acceptor = (S)-1-pyrroline-5-carboxylate + reduced acceptor.
    GO:0043565    sequence-specific DNA binding    Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
    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:0001141    transcriptional repressor activity, bacterial-type RNA polymerase core promoter proximal region sequence-specific binding    Interacting selectively and non-covalently with a sequence of DNA that is in cis with and relatively close to a core promoter for a bacterial-type RNA polymerase in order to stop, prevent, or reduce the frequency, rate or extent of transcription from a bacterial-type RNA polymerase promoter.
biological process
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    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:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0006561    proline biosynthetic process    The chemical reactions and pathways resulting in the formation of proline (pyrrolidine-2-carboxylic acid), a chiral, cyclic, nonessential alpha-amino acid found in peptide linkage in proteins.
    GO:0010133    proline catabolic process to glutamate    The chemical reactions and pathways resulting in the breakdown of proline into other compounds, including glutamate.
    GO:0006560    proline metabolic process    The chemical reactions and pathways involving proline (pyrrolidine-2-carboxylic acid), a chiral, cyclic, nonessential alpha-amino acid found in peptide linkage in proteins.
    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:0009898    cytoplasmic side of plasma membrane    The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
