The present invention provides a novel antibody format that does not use hetero-association technology and that is theoretically free of by-products having immune activity. This multispecific antibody has a Fab region that includes one polypeptide a chain and two polypeptide b chains. The polypeptide a chain includes a polypeptide in which a variable region Va1, a stationary region Ca1, a peptide linker LL, a variable region Va2 and a stationary region Ca are linked in the stated order. The polypeptide b chain includes a polypeptide in which a variable region Vb is linked to a stationary region Cb, which is linked to the stationary region Ca1 or the stationary region Ca2.

The present invention generally relates to methods of producing one or more indole diterpene compounds in the epoxy janthitrem biosynthetic pathway and polynucleotides, polypeptides, expression constructs and host cells useful in the production of one or more indole diterpene compounds, and methods of using same to confer a benefit to an organism, such as increased insect pest resistance.
