Function
function
Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate.
Catalytic activity
- (2E)-4-hydroxy-3-methylbut-2-enyl diphosphate + 2 H+ + H2O + oxidized [flavodoxin] = 2-C-methyl-D-erythritol 2,4-cyclic diphosphate + reduced [flavodoxin]
Cofactor
Note: Binds 1 [4Fe-4S] cluster.
Pathway
Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate: step 5/6.
