Title: Unusual Farnesyl Pyrophosphate Synthetase Reaction of an Artificial Substrate with Ni<sup>2+</sup>
Abstract: Abstract Farnesyl pyrophosphate (FPP) synthetase catalyzed the condensation of geranyl pyrophosphate (GPP) with 4-methyl-4-pentenyl pyro phosphate in the presence of Ni2+ to give an unexpected product, homofarnesyl pyrophosphate having an exomethylene group, together with Z-homofarnesyl pyrophosphate.
