p-Cymene Promotes Its Catabolism through the p-Cymene and the p-Cumate Pathways, Activates a Stress Response and Reduces the Biofilm Formation in Burkholderia xenovorans LB400
p-Cymene is an aromatic terpene that is present in diverse plant species. The aims of this study were to study the p-cymene metabolism in the model aromatic-degrading bacterium Burkholderia xenovorans LB400, and its response to p-cymene. The catabolic p-cymene (cym) and p-cumate (cmt) genes are clustered on the LB400 major chromosome. B. xenovorans LB400 was able to grow on p-cymene as well as ...
متن کاملCrystallization and properties of p-hydroxybenzoate hydroxylase from Pseudomonas putida.
1. The inducible p-hydroxybenzoate hydroxylase of Pseudomonas putidu which catalyzes the hydroxylation of P-hydroxybenzoate to protocatechuate has been obtained in crystalline form as a protein homogeneous upon ultracentrifugation and electrophoresis. The molecular weight is estimated to be 83,600. 2. The enzyme contains approximately 1 mole of flavin adenine dinucleotide per mole of protein. R...
متن کاملHerellea (Acinetobacter) and Pseudomonas ovalis (P. putida) from frozen foods.
Seventeen strains of Herellea vaginicola (Acinetobacter antitratus) and 8 of Pseudomonas ovalis (P. putida), isolated from 23 (6.3%) of 364 samples of frozen, foil-pack foods, were identified and characterized morphologically and biochemically. Herellea was isolated from 17 foods (4.7%), P. ovalis from 6 (1.6%). No Mima were found. The food samples included precooked frozen meats, precooked and...
متن کاملp-Hydroxyphenylacetic Acid Metabolism in Pseudomonas putida F6.
Pseudomonas putida F6 was found to metabolize p-hydroxyphenylacetic acid through 3,4-dihydroxyphenylacetic acid, 3,4-dihydroxymandelic acid, and 3,4-dihydroxybenzaldehyde. Cell extracts of P. putida F6 catalyze the NAD(P)H-independent hydroxylation of p-hydroxyphenylacetic acid to 3,4-dihydroxyphenylacetic acid which is further oxidized to 3,4-dihydroxymandelic acid. Oxidation and decarboxylati...
متن کاملExpansion of growth substrate range in Pseudomonas putida F1 by mutations in both cymR and todS, which recruit a ring-fission hydrolase CmtE and induce the tod catabolic operon, respectively.
Pseudomonas putida F1 can assimilate benzene, toluene and ethylbenzene using the toluene degradation pathway, and can also utilize p-cymene via p-cumate using the p-cymene and p-cumate catabolic pathways. In the present study, P. putida F1 strains were isolated that were adapted to assimilate new substrates such as n-propylbenzene, n-butylbenzene, cumene and biphenyl, and the molecular mechanis...
