STRUCTURE AND MECHANISM OF ACTION OF ISOPENTENYLPYROPHOSPHATE-DIMETHYLALLYLPYROPHOSPHATE ISOMERASE: COMPLEX OF C67A MUTANT WITH EIPP


Overview

Isopentenyl diphosphate:dimethylallyl diphosphate (IPP:DMAPP) isomerase is a key enzyme in the biosynthesis of isoprenoids. The mechanism of the isomerization reaction involves protonation of the unactivated carbon-carbon double bond in the substrate. Analysis of the 1.97 A crystal structure of the inactive C67A mutant of E. coli isopentenyl diphosphate:dimethylallyl diphosphate isomerase complexed with the mechanism-based inactivator 3,4-epoxy-3-methyl-1-butyl diphosphate is in agreement with an isomerization mechanism involving Glu 116, Tyr 104, and Cys 67. In particular, the results are consistent with a mechanism where Glu116 is involved in the protonation step and Cys67 in the elimination step.
