phenol and benzoate metabolism by pseudomonas putida: regulation of tangential pathways.catechol occurs as an intermediate in the metabolism of both benzoate and phenol by strains of pseudomonas putida. during growth at the expense of benzoate, catechol is cleaved ortho (1,2-oxygenase) and metabolized via the beta-ketoadipate pathway; during growth at the expense of phenol or cresols, the catechol or substituted catechols formed are metabolized by a separate pathway following meta (2,3-oxygenase) cleavage of the aromatic ring of catechol. it is possible to explain the mutually excl ...19695354952
regulation of the meta cleavage pathway for benzoate oxidation by pseudomonas putida.catechol or 2-hydroxymuconic semialdehyde cannot participate as functional inducers of the meta pathway for benzoate metabolism in pseudomonas putida. induction of the first two enzymes of the pathway must be mediated by benzoate, or its analogues, as primary substrate.19695359614
