Chain A,C   (EUTB_ECOLI | P0AEJ6)
molecular function
    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:0008851    ethanolamine ammonia-lyase activity    Catalysis of the reaction: ethanolamine = acetaldehyde + NH3.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
    GO:0006520    cellular amino acid metabolic process    The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells.
    GO:0046336    ethanolamine catabolic process    The chemical reactions and pathways resulting in the breakdown of ethanolamine (2-aminoethanol), an important water-soluble base of phospholipid (phosphatidylethanolamine).
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.
    GO:0009350    ethanolamine ammonia-lyase complex    An enzyme complex that catalyzes the breakdown of ethanolamine to form acetaldehyde and ammonia.

Chain B,D   (EUTC_ECOLI | P19636)
molecular function
    GO:0031419    cobalamin binding    Interacting selectively and non-covalently with cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.
    GO:0008851    ethanolamine ammonia-lyase activity    Catalysis of the reaction: ethanolamine = acetaldehyde + NH3.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond.
