molecular function
    GO:0052936    2-chloroethanol:cytochrome c oxidoreductase activity    Catalysis of the reaction: 2-chloroethanol + 2 cytochrome c = chloroacetaldehyde + 2 reduced cytochrome c.
    GO:0018468    alcohol dehydrogenase (acceptor) activity    Catalysis of the reaction: a primary alcohol + acceptor = an aldehyde + reduced acceptor.
    GO:0052934    alcohol dehydrogenase (cytochrome c) activity    Catalysis of the reaction: primary alcohol + 2 cytochrome c = 2 reduced cytochrome c + an aldehyde + 2 H+.
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0052935    ethanol:cytochrome c oxidoreductase activity    Catalysis of the reaction: ethanol + 2 cytochrome c = 2 reduced cytochrome c + acetaldehyde.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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:0016614    oxidoreductase activity, acting on CH-OH group of donors    Catalysis of an oxidation-reduction (redox) reaction in which a CH-OH group act as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
biological process
    GO:0006069    ethanol oxidation    An ethanol metabolic process in which ethanol is converted to acetyl-CoA via acetaldehyde and acetate.
    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:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0030288    outer membrane-bounded periplasmic space    The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
    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).
