Catabolic Plasmids
Formost of this century agriculture and industry haveused a wide range of synthetic chemicals which appear to have no counterparts in nature. Many of these compounds, by their very nature and complexity, are resistant to degradation when released into soil, water and air. Unfortunately, the repeated use and release of such synthetics has become an everyday occurrence, resulting in widespread en...
متن کاملConvergent evolution of Amadori opine catabolic systems in plasmids of Agrobacterium tumefaciens.
Deoxyfructosyl glutamine (DFG, referred to elsewhere as dfg) is a naturally occurring Amadori compound found in rotting fruits and vegetables. DFG also is an opine and is found in tumors induced by chrysopine-type strains of Agrobacterium tumefaciens. Such strains catabolize this opine via a pathway coded for by their plasmids. NT1, a derivative of the nopaline-type A. tumefaciens strain C58 la...
متن کاملComparison of Four Comamonas Catabolic Plasmids Reveals the Evolution of pBHB To Catabolize Haloaromatics.
Comamonas plasmids play important roles in shaping the phenotypes of their hosts and the adaptation of these hosts to changing environments, and understanding the evolutionary strategy of these plasmids is thus of great concern. In this study, the sequence of the 119-kb 3,5-dibromo-4-hydroxybenzonitrile-catabolizing plasmid pBHB from Comamonas sp. strain 7D-2 was studied and compared with those...
متن کاملQuorum-sensing signal production by Agrobacterium vitis strains and their tumor-inducing and tartrate-catabolic plasmids.
Agrobacterium vitis strains, their tumor-inducing (pTi) and tartrate utilization (pTr) plasmid transconjugants and grapevine tumors were analyzed for the presence of N-acyl-homoserine lactones (AHLs). All wild-type A. vitis strains produced long-chain signals. PCR analysis of the A. vitis long-chain AHL synthase gene, avsI, showed the predicted amplicon. Agrobacterium tumefaciens UBAPF2 harbori...
متن کاملIdentification and characterization of the nitrobenzene catabolic plasmids pNB1 and pNB2 in Pseudomonas putida HS12.
Pseudomonas putida HS12, which is able to grow on nitrobenzene, was found to carry two plasmids, pNB1 and pNB2. The activity assay experiments of wild-type HS12(pNB1 and pNB2), a spontaneous mutant HS121(pNB2), and a cured derivative HS124(pNB1) demonstrated that the catabolic genes coding for the nitrobenzene-degrading enzymes, designated nbz, are located on two plasmids, pNB1 and pNB2. The ge...
