Chain A,B,C,D   (PAND_ECOLI | P0A790)
molecular function
    GO:0004068    aspartate 1-decarboxylase activity    Catalysis of the reaction: L-aspartate = beta-alanine + CO2.
    GO:0016831    carboxy-lyase activity    Catalysis of the nonhydrolytic addition or removal of a carboxyl group to or from a compound.
    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:0006523    alanine biosynthetic process    The chemical reactions and pathways resulting in the formation of alanine, 2-aminopropanoic acid.
    GO:0015940    pantothenate biosynthetic process    The chemical reactions and pathways resulting in the formation of pantothenate, the anion of pantothenic acid. It is a B complex vitamin that is a constituent of coenzyme A and is distributed ubiquitously in foods.
    GO:0016540    protein autoprocessing    Processing which a protein carries out itself. This involves actions such as the autolytic removal of residues to generate the mature form of the protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
