Chain A   (1A1C_MALDO | P37821)
molecular function
    GO:0016847    1-aminocyclopropane-1-carboxylate synthase activity    Catalysis of the reaction: S-adenosyl-L-methionine(1+) = 1-aminocyclopropane-1-carboxylate + S-methyl-5'-thioadenosine + H(+).
    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: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.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    GO:0030170    pyridoxal phosphate binding    Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6.
biological process
    GO:0042218    1-aminocyclopropane-1-carboxylate biosynthetic process    The chemical reactions and pathways resulting in the formation of 1-aminocyclopropane-1-carboxylate, a natural product found in plant tissues. It is a key intermediate in the biosynthesis of ethylene (ethene), a fruit-ripening hormone in plants.
    GO:0009058    biosynthetic process    The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
    GO:0009693    ethylene biosynthetic process    The chemical reactions and pathways resulting in the formation of ethylene (C2-H4, ethene), a simple hydrocarbon gas that can function in plants as a growth regulator.
    GO:0009835    fruit ripening    An aging process that has as participant a fruit. Ripening causes changes in one or more characteristics of a fruit (color, aroma, flavor, texture, hardness, cell wall structure) and may make it more attractive to animals and aid in seed dispersal.
