Xanthohumol

Thaumatin is a natural α+β-protein which is synthesized by the katamfe plant (Thaumatococcus daniellii), it is said to be 2.000 to 100.000 times sweeter than sucrose on molar basis, but the sweetness builds slow and lasts long. It has been approved as a sweetener by the European Union (E957). Our aim is to have S. cerevisiae secrete functional Thaumatin by expressing Preprothaumatin – a principle which has been proven by Edens et al. in 1984.(1)
