Catechol 2,3-dioxygenase encoded by TOL plasmid pWW0 of Pseudomonas putida consists of four identical subunits, each containing one ferrous ion. The enzyme catalyzes ring cleavage of catechol, 3-methylcatechol, and 4-methylcatechol but shows only weak activity toward 4-ethylcatechol. Two mutants of

A purification procedure has been developed for an extradiol dioxygenase expressed in Escherichia coli, which was originally derived from a Pseudomonas putida strain able to grow on toluidine. Physical and kinetic properties of the enzyme have been investigated. The enzyme

Bioproduction of 3-methylcatechol from toluene by Pseudomonas putida MC2 was studied in the presence of an additional 1-octanol phase. This solvent was used to supply the substrate and extract the product, in order to keep the aqueous concentrations low. A

Applied microbiology and biotechnology, 54(2), 180-185 (2000-09-01)
The aim of the study was to investigate whether toxic fine chemical production can be improved using the solvent-tolerant Pseudomonas putida S12 in a two-liquid-phase system consisting of aqueous media and a water-immiscible octanol phase with production of 3-methylcatechol from
L E Hüsken et al.
Journal of biotechnology, 88(1), 11-19 (2001-05-30)
Pseudomonas putida MC2 is a solvent-tolerant strain that accumulates 3-methylcatechol. In aqueous media, 10 mM of 3-methylcatechol was produced and production was limited by 3-methylcatechol toxicity to the biocatalyst. Production levels increased by introduction of a second, organic phase that
