CC -!- FUNCTION: Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-
CC 2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate.
CC {ECO:0000255|HAMAP-Rule:MF_00159}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E)-4-hydroxy-3-methylbut-2-enyl diphosphate + 2 H(+) + H2O +
CC oxidized [flavodoxin] = 2-C-methyl-D-erythritol 2,4-cyclic
CC diphosphate + reduced [flavodoxin]; Xref=Rhea:RHEA:43604, Rhea:RHEA-
