Chain A   (AZUR_PSEAE | P00282)
molecular function
    GO:0005507    copper ion binding    Interacting selectively and non-covalently with copper (Cu) ions.
    GO:0009055    electron carrier activity    Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    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).
