Table 1. Degree of identity between amino acid sequences encoding FMOs of Z. variegatus, other insects, and the FMO1 of human.

(%)	ZvFMOa	ZvFMOc	ZvPNO	TjSNO	DmFMO3006	DmFMO3174	HsFMO1
ZvFMOa	100	77.0	77.8	35.2	36.4	36.3	39.8
ZvFMOc			77.0	35.3	38.2	36.6	38.8
ZvPNO				36.3	38.2	37.1	37.7

For comparison, the full coding regions were used. TjSNO, Senecionine N-oxygenase of Tyria jacobaeae; DmFMO3006 and DmFMO3174, FMO sequences of unknown function present in the genome of Drosophila melanogaster; HsFMO1, FMO1 of human.
