ENZYME entry: EC 4.1.3.36

Accepted Name
1,4-dihydroxy-2-naphthoyl-CoA synthase.
Alternative Name(s)
DHNA synthetase.
dihydroxynaphthoic acid synthetase.
naphthoate synthase.
o-succinylbenzoyl-CoA 1,4-dihydroxy-2-naphthoate-lyase (cyclizing).
Reaction catalysed
2-succinylbenzoyl-CoA + H(+) <=> 1,4-dihydroxy-2-naphthoyl-CoA + H2O
Comment(s)
  • This enzyme is involved in the synthesis of 1,4-dihydroxy-2- naphthoate, a branch point metabolite leading to the biosynthesis of menaquinone (vitamin K2, in bacteria), phylloquinone (vitamin K1 in plants), and many plant pigments.
  • The coenzyme A group is subsequently removed from the product by EC 3.1.2.28.
