Abstract
Genes for the alpha and beta subunits of the enzyme protocatechuate 3,4-dioxygenase were cloned from the Pseudomonas cepacia DB01 chromosome on a 9.5 kilobase pair PstI fragment into the broad-host-range cloning vector pR02317. The resultant clone was able to complement protocatechuate 3,4-dioxygenase mutations in P. cepacia, P. aeruginosa, and P. putida. Expression studies showed that the genes were constitutively expressed and subject to catabolite repression in the heterologous host. Since the cloned genes exhibited normal induction patterns when present in P. cepacia DB01 it was concluded that induction was subject to negative control.
