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

IspH, also called LytB, a protein involved in the biosynthesis of isoprenoids through the methylerythritol phosphate pathway, is an attractive target for the development of new antimicrobial drugs. Here, we report crystal structures of Escherichia coli IspH in complex with the two most potent inhibitors: (E)-4-mercapto-3-methylbut-2-en-1-yl diphosphate (TMBPP) and (E)-4-amino-3-methylbut-2-en-1-yl diphosphate (AMBPP) at 1.95 and 1.7 A resolution, respectively. The structure of the E. coli IspH:TMBPP complex exhibited two conformers of the inhibitor. This unexpected feature was exploited to design and evolve new antimicrobial candidates in silico.
