Catalyzes the hydrolysis of 1,4-dihydroxy-2-naphthoyl-CoA (DHNA-CoA) to 1,4-dihydroxy-2-naphthoate (DHNA), a reaction involved in phylloquinone (vitamin K1) biosynthesis. 1,4-dihydroxy-2-naphthoyl-CoA + H2O = 1,4-dihydroxy-2-naphthoate + CoA + H(+) Cofactor biosynthesis; phylloquinone biosynthesis. Quinol/quinone metabolism; 1,4-dihydroxy-2-naphthoate biosynthesis; 1,4-dihydroxy-2-naphthoate from chorismate: step 7/7. Belongs to the 4-hydroxybenzoyl-CoA thioesterase family. DHNA-CoA hydrolase subfamily.
