title: Biosynthesis of terpenoids: efficient multistep biotransformation procedures affording isotope-labeled 2C-methyl-D-erythritol 4-phosphate using recombinant 2C-methyl-D-erythritol 4-phosphate synthase.
abstract: This paper describes the recombinant expression of the ispC gene of Escherichia coli specifying 2C-methyl-D-erythritol 4-phosphate synthase in a modified form that can be purified efficiently by metal-chelating chromatography. The enzyme was used for the preparation of isotope-labeled 2C-methyl-D-erythritol 4-phosphate employing isotope-labeled glucose and pyruvate as starting materials. The simple one-pot methods described afford numerous isotopomers of 2C-methyl-D-erythritol 4-phosphate carrying (3)H, (13)C, or (14)C from commercially available precursors. The overall yield based on the respective isotope-labeled starting material is approximately 50%.
