   2.3.1.165 | acetyl-CoA + 3 malonyl-CoA + NADPH + H+ = 6-methylsalicylate + 4 CoA + 3 CO2 + NADP+ + H2O |
6-methylsalicylate synthesis proceeds without catalytic dehydration of the beta-hydroxy triketide intermediate by DH domain which is therefore not required for tetraketide formation. The subsequent aldol cyclization and aromatization of the tetraketide intermediate then form 6-methylsalicylate covalently bound to the ACP phosphopantetheine arm as the thioester. 6-methylsalicylate is released hydrolytically from ATX by the action of the domain hitherto called DH domain, i.e. the thioester hydrolase catalytic domain |

| 2.3.1.165 | acetyl-CoA + 3 malonyl-CoA + NADPH + H+ = 6-methylsalicylate + 4 CoA + 3 CO2 + NADP+ + H2O |
a multienzyme complex with a 4'-phosphopantetheine prosthetic group on the acyl carrier protein, it has a similar sequence to vertebrate type I fatty acid synthase, acetoacetyl-CoA can also act as a starter molecule |
