Chain A,B   (TRI5_FUSSP | P13513)
molecular function
    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:0045482    trichodiene synthase activity    Catalysis of the reaction: 2-trans,6-trans-farnesyl diphosphate = diphosphate + trichodiene.
biological process
    GO:0016106    sesquiterpenoid biosynthetic process    The chemical reactions and pathways resulting in the formation of sesquiterpenoid compounds, terpenoids with three isoprene units.
