title: Dispersed family of human genes with sequence similarity to farnesyl pyrophosphate synthetase.
abstract: Prenyltransferases are a group of enzymes involved in the biosynthesis of both sterol and nonsterol isoprene compounds. Somatic cell hybrid studies and in situ hybridization show that the human genome contains five distinct loci that hybridize to the cDNA for the enzyme farnesyl pyrophosphate synthetase (FPS), a prenyltransferase that catalyzes the synthesis of an intermediate common to both the sterol and the nonsterol branches of the isoprene biosynthetic pathway. The loci identified in this report may correspond to unique prenyltransferase genes related to FPS or to pseudogenes. The loci mapped have been identified as farnesyl pyrophosphate synthetase-"like"-1 (FPSL-1) on chromosome 1q24-31, FPSL-2 on chromosome 7, FPSL-3 on chromosome 14, FPSL-4 on chromosome 15q14-q21, and FPSL-5 on chromosome Xq21-22. Multiple copies of sequences similar to those of FPS are also present in both the mouse and the rat.
