An improved spectrophotometric assay for monoamine oxidase in mitochondria
other Rhizobium species. Most of these plasmids encoding for fixation and nodulation properties are non-self transmissible. Plasmid profiles were determined for 24 strains of R. trifolii. All the strains harboured at least three plasmids and as many as eight were present in some strains. Southern hybridization with cloned R. meliloti nifgenes was used to identify indigenous Nif plasmids. Each s...
متن کاملMapping of Streptococcus faecalis plasmids pAD1 and pAD2 and studies relating to transposition of Tn917.
Plasmids pAD1 (37.8 megadaltons) and pAD2 (17.1 megadaltons) of Streptococcus faecalis strain DS16 have been mapped with restriction enzymes. The location of a hemolysin-bacteriocin determinant on the conjugative pAD1 plasmid was derived from analyses of transposon insertions. Electron microscope and hybridization analyses located Tn917(Em) and the streptomycin (Sm) and kanamycin (Km) resistanc...
متن کاملConversion of pBR322-based plasmids into broad-host-range vectors by using the Tn3 transposition mechanism.
We constructed a series of transposon vectors which allow efficient in vitro gene manipulation and subsequent introduction of cloned DNA into a variety of gram-negative bacteria. Transfer of the cloned fragment from these multicopy plasmids into self-transmissible broad-host-range vectors is achieved in vivo, using the Tn3 transposition mechanism. Transposition into a variety of broad-host-rang...
متن کاملInsertion Sequence IS26 Reorganizes Plasmids in Clinically Isolated Multidrug-Resistant Bacteria by Replicative Transposition
UNLABELLED Carbapenemase-producing Enterobacteriaceae (CPE), which are resistant to most or all known antibiotics, constitute a global threat to public health. Transposable elements are often associated with antibiotic resistance determinants, suggesting a role in the emergence of resistance. One insertion sequence, IS26, is frequently associated with resistance determinants, but its role remai...
