Transfer and expression of degradative and antibiotic resistance plasmids in acidophilic bacteria.
The genetic accessibility of selected acidophilic bacteria was investigated to evaluate their applicability to degrading pollutants in acidic environments. The IncP1 antibiotic resistance plasmids RP4 and pVK101 and the phenol degradation-encoding plasmid pPGH11 were transferred from neutrophilic bacteria into the extreme acidophilic eubacterium Acidiphilium cryptum at frequencies of 1.8 x 10(-...
متن کاملCharacterization of diverse 2,4-dichlorophenoxyacetic acid-degradative plasmids isolated from soil by complementation.
The diversity of 2,4-dichlorophenoxyacetic acid (2,4-D)-degradative plasmids in the microbial community of an agricultural soil was examined by complementation. This technique involved mixing a suitable Alcaligenes eutrophus (Rifr) recipient strain with the indigenous microbial populations extracted from soil. After incubation of this mixture, Rifr recipient strains which grow with 2,4-D as the...
متن کاملDetection and characterization of conjugative degradative plasmids in xenobiotic-degrading Sphingomonas strains.
A systematic survey for the presence of plasmids in 17 different xenobiotic-degrading Sphingomonas strains was performed. In almost all analyzed strains, two to five plasmids with sizes of about 50 to 500 kb were detected by using pulsed-field gel electrophoresis. A comparison of plasmid preparations untreated or treated with S1 nuclease suggested that, in general, Sphingomonas plasmids are cir...
متن کاملDegradative enzymes in osteoarthritis.
A central feature of the osteoarthritic disease process involves erosive destruction of the articular cartilage extracellular matrix (ECM) on the surfaces of diarthrotic joints. The resultant loss of joint function makes studies on mechanisms underlying ECM degradation critical for treatment of the disease and prevention of disability. Candidate pathways to account for the loss of cartilage inv...
متن کاملRegulation of signaling by non-degradative ubiquitination.
Acentral unifying principle in the field of signal transduction has been the covalent modification of proteins by phosphorylation. A wide range of protein kinases are known, and the process is regulated by a more limited although important number of protein phosphatases. Recently, there has been a remarkable increase in the numbers of examples of another reversible covalent modification in prot...
