Biphenyls and dibenzofurans are the phytoalexins of the Pyrinae, a subtribe of the plant family Rosaceae. The Pyrinae correspond to the long-recognized Maloideae. Economically valuable species of the Pyrinae are apples and pears. Biphenyls and dibenzofurans are formed de novo...

A previous study showed that benzoate was catabolized via a coenzyme A (CoA)-dependent epoxide pathway in Azoarcus evansii (R. Niemetz, U. Altenschmidt, S. Brucker, and G. Fuchs, Eur. J. Biochem. 227:161-168, 1995), but gentisate 1,2-dioxygenase was induced. Similarly, we found...

Type III polyketide synthases (PKSs) generate a diverse array of secondary metabolites by varying the starter substrate, the number of condensation reactions, and the mechanism of ring closure. Among the starter substrates used, benzoyl-CoA is a rare starter molecule. Biphenyl...

Volatile esters are key compounds of kiwifruit flavour and are formed by alcohol acyltransferases that belong to the BAHD acyltransferase superfamily. Quantitative RT-PCR was used to screen kiwifruit-derived expressed sequence tags with proposed acyltransferase function in order to select ripening-specific...

Sorbus aucuparia cell cultures accumulate biphenyl and dibenzofuran phytoalexins in response to elicitor treatment. These polyketide derivatives arise from the starter substrate benzoyl-CoA, the biosynthesis of which is largely unresolved. Two CoA ligases involved are cinnamate:CoA ligase and benzoate:CoA ligase...

BoxA is the reductase component of the benzoyl-coenzyme A (CoA) oxidizing epoxidase enzyme system BoxAB. The enzyme catalyzes the key step of an hitherto unknown aerobic, CoA-dependent pathway of benzoate metabolism, which is the epoxidation of benzoyl-CoA to the non-aromatic...

The coenzyme A (CoA)-dependent aerobic benzoate metabolic pathway uses an unprecedented chemical strategy to overcome the high aromatic resonance energy by forming the non-aromatic 2,3-epoxybenzoyl-CoA. The crucial dearomatizing reaction is catalyzed by three enzymes, BoxABC, where BoxA is an NADPH-dependent...
