Chain A,B,C,D   (FRE_ECOLI | P0AEN1)
molecular function
    GO:0052873    FMN reductase (NADPH) activity    Catalysis of the reaction: FMNH2 + NADP+ = FMN + NADPH + 2 H+.
    GO:0047138    aquacobalamin reductase activity    Catalysis of the reaction: 2 cob(II)alamin + NAD+ = 2 aquacob(III)alamin + NADH + H+.
    GO:0008047    enzyme activator activity    Binds to and increases the activity of an enzyme.
    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:0052875    riboflavin reductase (NADH) activity    Catalysis of the reaction: reduced riboflavin + NAD+ = riboflavin + NADH + 2 H+.
    GO:0042602    riboflavin reductase (NADPH) activity    Catalysis of the reaction: reduced riboflavin + NADP+ = riboflavin + NADPH + 2 H+.
biological process
    GO:0006811    ion transport    The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0055072    iron ion homeostasis    Any process involved in the maintenance of an internal steady state of iron ions within an organism or cell.
    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:0043085    positive regulation of catalytic activity    Any process that activates or increases the activity of an enzyme.
    GO:0030091    protein repair    The process of restoring a protein to its original state after damage by such things as oxidation or spontaneous decomposition of residues.
    GO:0006979    response to oxidative stress    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
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.
