Theoretical Model(hide GO term definitions)
Chain A   (PRX2_PENRO | Q03471)
molecular function
    GO:0045483    aristolochene synthase activity    Catalysis of the reaction: trans,trans-farnesyl diphosphate = aristolochene + diphosphate.
    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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
