Metabolism of aromatic compounds by Caulobacter crescentus.
Cultures of Caulobacter crescentus were found to grow on a variety of aromatic compounds. Degradation of benzoate, p-hydroxybenzoate, and phenol was found to occur via beta-ketoadipate. The induction of degradative enzymes such as benzoate 1,2-dioxygenase, the ring cleavage enzyme catechol 1,2-dioxygenase, and cis, cis-muconate lactonizing enzyme appeared similar to the control mechanism presen...
متن کاملAnaerobic metabolism of aromatic compounds.
Aromatic compounds comprise a wide variety of natural and synthetic compounds that can serve as substrates for bacterial growth. So far, four types of aromatic metabolism are known. (1) The aerobic aromatic metabolism is characterized by the extensive use of molecular oxygen as cosubstrate for oxygenases that introduce hydroxyl groups and cleave the aromatic ring. (2) In the presence of oxygen,...
متن کاملBiosynthesis of polybrominated aromatic organic compounds by marine bacteria
Polybrominated diphenyl ethers (PBDEs) and polybrominated bipyrroles are natural products that bioaccumulate in the marine food chain. PBDEs have attracted widespread attention because of their persistence in the environment and potential toxicity to humans. However, the natural origins of PBDE biosynthesis are not known. Here we report marine bacteria as producers of PBDEs and establish a gene...
متن کاملMetabolism of Aromatic Compounds in Bacteria PURIFICATIOK AND PROPERTIES OF THE CATECHOL-FORMING
The conversion of 3,5-cyclohexadiene-1 J-diol-l-carboxylic acid (DHB) to catechol has been shown to be catalyzed by a single protein from the bacterium Alcaligenes eutrophus. The enzyme was purified by ultracentrifugation, ammonium sulfate fractionation, DEAE-cellulose chromatography and Sephadex G-ZOO gel filtration. Its molecular weight is approximately 94,600 (by sedimentation equilibrium) a...
متن کاملEffects of polyhalogenated aromatic compounds on porphyrin metabolism.
Heme production is a vital metabolic process that occurs in the bone marrow and liver. Porphyrins are unused by-products of this biosynthetic process and normally occur in urine and other body fluids in low concentrations. Various disorders can disrupt the heme biosynthetic process, causing greater quantities of porphyrins in urine. The porphyrias are a group of diseases characterized by excess...
