Catalyzes the hydrolysis of 1,4-dihydroxy-2-naphthoyl-CoA (DHNA-CoA) to 1,4-dihydroxy-2-naphthoate (DHNA). Also shows significant activity toward a wide range of acyl-CoA thioesters, and minimal activity toward benzoyl-holoEntB. 1,4-dihydroxy-2-naphthoyl-CoA + H2O = 1,4-dihydroxy-2-naphthoate + CoA + H(+) kcat is 6.2 sec(-1) with 1,4-dihydroxy-2-naphthoyl-CoA (PubMed:23564174). kcat is 1.6 sec(-1) with 1,4-dihydroxy-2-naphthoyl-CoA (PubMed:24992697). kcat is 0.12 sec(-1) with oleoyl-CoA. kcat is 0.62 sec(-1) with myristoyl-CoA. kcat is 0.0044 sec(-1) with acetyl-CoA. kcat is 0.58 sec(-1) with palmitoyl-CoA. kcat is 0.74 sec(-1) with lauroyl-CoA. kcat is 14.8 sec(-1) with 1-hydroxy-2-naphthoyl-CoA. kcat is 5.2 sec(-1) with 4-hydroxybenzoyl-CoA. kcat is 0.3 sec(-1) with hexanoyl-CoA. kcat is 17.7 sec(-1) with benzoyl-CoA. kcat is 12.6 sec(-1) with 3,5-dihydroxybenzoyl-CoA. kcat is 23.2 sec(-1) with 3,4-dihydroxybenzoyl-CoA. kcat is 8.4 sec(-1) with coumaroyl-CoA. kcat is 0.083 sec(-1) with benzoyl-ACP. kcat is 0.5 sec(-1) with beta-methylcrotonyl-CoA. kcat is 93.0 sec(-1) with salicylyl-CoA. kcat is 0.67 sec(-1) with beta-methylmalonyl-CoA. kcat is 0.21 sec(-1) with propionyl-CoA. kcat is 0.0036 sec(-1) with 2,4-dihydroxybenzoyl-EntB. Quinol/quinone metabolism; 1,4-dihydroxy-2-naphthoate biosynthesis; 1,4-dihydroxy-2-naphthoate from chorismate: step 7/7. Quinol/quinone metabolism; menaquinone biosynthesis. Homotetramer. Dimer of dimers. Deletion results in a significant decrease in menaquinone production. Belongs to the thioesterase PaaI family.
