Characterization of a novel aphid prenyltransferase displaying dual geranyl/farnesyl diphosphate synthase activity.

abstract：:Steroids are of universal occurrence, present variously as cell wall constituents and bioregulators. A number of bacteria, fungi, and photosynthetic vascular plants synthesize steroids that are hormonally active in the animal world. The cellular effect of such steroids in microbes and plants appears by and large to be...
