CATH Classification

Domain Context

CATH Clusters

Superfamily Sulfite Reductase Hemoprotein, domain 1
Functional Family 4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase (flavodoxin)

Enzyme Information

1.17.7.3
(E)-4-hydroxy-3-methylbut-2-enyl-diphosphate synthase (flavodoxin).
based on mapping to UniProt O67496
(E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + H(2)O + oxidized flavodoxin = 2-C-methyl-D-erythritol 2,4-cyclodiphosphate + reduced flavodoxin.
-!- Forms part of an alternative non-mevalonate pathway for isoprenoid biosynthesis that is found in most bacteria. -!- Plants and cyanobacteria have a similar enzyme that utilizes ferredoxin rather than flavodoxin (cf. EC 1.17.7.1).
