Chain A   (NIR_ACHCY | P25006)
molecular function
    GO:0005507    copper ion binding    Interacting selectively and non-covalently with copper (Cu) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0050421    nitrite reductase (NO-forming) activity    Catalysis of the reaction: nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+.
    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.
biological process
    GO:0019333    denitrification pathway    The reduction of nitrate to dinitrogen by four reactions; each intermediate is transformed to the next lower oxidation state; also part of cellular bioenergetics; the nitrogen compounds can serve as terminal acceptors for electron transport phosphorylation in place of oxygen.
    GO:0042128    nitrate assimilation    The nitrogen metabolic process that encompasses the uptake of nitrate from the environment and reduction to ammonia, and results in the incorporation of nitrogen derived from nitrate into cellular substances.
    GO:0006807    nitrogen compound metabolic process    The chemical reactions and pathways involving organic or inorganic compounds that contain nitrogen.
    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.
cellular component
    GO:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
