Characterization of Pseudomonas putida mutants unable to catabolize benzoate: cloning and characterization of Pseudomonas genes involved in benzoate catabolism and isolation of a chromosomal DNA fragment able to substitute for xylS in activation of the TOL lower-pathway promoter.

Abstract excerpt

Mutants of Pseudomonas putida mt-2 that are unable to convert benzoate to catechol were isolated and grouped into two classes: those that did not initiate attack on benzoate and those that accumulated 3,5-cyclohexadiene-1,2-diol-1-carboxylic acid (benzoate diol). The latter mutants, represents by strain PP0201, were shown to lack benzoate diol dehydrogenase (benD) activity. Mutants from the former class were...
