Asymmetric Unit(hide GO term definitions)
Chain A,B   (CFI3_ARATH | Q8VZW3)
molecular function
    GO:0045430    chalcone isomerase activity    Catalysis of the reaction: a chalcone = a flavanone.
    GO:0016872    intramolecular lyase activity    The catalysis of certain rearrangements of a molecule to break or form a ring.
    GO:0016853    isomerase activity    Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
biological process
    GO:0009813    flavonoid biosynthetic process    The chemical reactions and pathways resulting in the formation of flavonoids, a group of phenolic derivatives containing a flavan skeleton.
    GO:0080167    response to karrikin    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a karrikin stimulus. Karrikins are signaling molecules in smoke from burning vegetation that trigger seed germination for many angiosperms (flowering plants).
