Function
ISPH_ECOLI Converts 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate into isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Is also involved in penicillin tolerance and control of the stringent response. Seems to directly or indirectly interact with RelA to maintain it in an inactive form during normal growth.[1] [2] [3]
Publication Abstract from PubMed
The iron-sulfur protein IspH catalyzes a key step in isoprenoid biosynthesis in bacteria and malaria parasites. Crystal structures of IspH complexed with three substrate analogues reveal their mode of binding and suggest new routes to inhibitor design.
