4-hydroxy-3-methylbut-2-enyl diphosphate reductase (P62623)

Identification
Name:4-hydroxy-3-methylbut-2-enyl diphosphate reductase
Synonyms:Not Available
Gene Name:ispH
Enzyme Class:
Biological Properties
General Function:Involved in isopentenyl diphosphate biosynthetic process, mevalonate-independent pathway
Specific Function: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
