1,4-dihydroxy-2-naphthoyl-CoA synthase  M-CSA #346

Naphthoate synthase (MenB, also known as 1,4-dihydroxy-2-naphthoyl-CoA synthase) 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 1,4-dihydroxy-2-naphthoyl-CoA hydrolase (EC:3.1.2.28). It is a member of the crotonase superfamily.
