title: Farnesyl pyrophosphate synthetase located in microsomes from pig liver.
abstract: The microsomes from pig liver contained farnesyl pyrophosphate synthetase and it was solubilized with Triton X-100. The microsomal enzyme had a pH optimum of 6.5-7.0 and required Mg2+ or Mn2+ for maximum activity. Dimethylallyl-transferring activity of the enzyme was much lower compared with the geranyl-transferring activity. In the presence of Triton X-100, the geranyl-transferring activity was about two-fold activated whereas the dimethylallyl-transferring activity was almost the same.
