A 46.8-kb plasmid, pBM309, of Bacillus megaterium determines the production of a bacteriocin, megacin A, and confers immunity against this antibiotic on the host cells. The megacin A (megA) and megacin A-immunity (megAim) genes were mapped on the physical map of pBM309 by using its deletion derivatives. Both genes were isolated as a 10.6-kb PstI fragment and cloned in Bacillus subtilis vector plasmid pBD9 for expression in B. megaterium. 
Molecular cloning of structural and immunity genes for megacins A-216 and A-19213 in Bacillus megaterium
A host-vector system was developed for molecular cloning in Bacillus megaterium and used to clone the structural and immunity genes for megacins A-216 and A-19213. Recombinant clones that expressedExpand
Cloning and Characterization of the DNA Region Responsible for Megacin A-216 Production in Bacillus megaterium 216
TLDR
Comparison of different megacin preparations suggests that the intact chain as well as the two combined fragments can form biologically active megacIn, and an ORF located next to the megA gene and encoding a 91-amino-acid protein was shown to be responsible for the relative immunity displayed by the producer strain against megac in A-216.

TLDR
Killing of sensitive bacteria by enterolysin A showed a dose-response behavior, and the bacteriocin has a bacteriolytic mode of action. Expand

Bacteriocinogenesis in Bacillus megaterium.
TLDR
A strain of Bacillus megaterium has been found under certain conditions to liberate a bacteriocin-like agent which has been termed megacin, which differs from bacteriophage in not giving rise to any further production of antibacterial principle, after acting on bacterial cells. Expand
Characterization of chimeric plasmid cloning vehicles in Bacillus subtilis.
TLDR
Seven chimeric plasmids that may be used for molecular cloning in Bacillus subtilis carry multiple antibiotic resistance markers and were constructed by in vitro molecular cloning techniques to identify proteins involved in plasmid-coded kanamycin and erythromycin resistance. Expand
Characterization of the plasmids of Bacillus megaterium: restriction endonuclease digestions, Southern blotting analysis, and partial denaturation mapping.
TLDR
It is concluded that each plasmid species, and probably the larger ones as well, represents a molecular entity of unique and distinct nucleotide sequence, unrelated to each other or to the chromosome of the bacterium. Expand

TLDR
The products of several megacinogenic strains of Bacillus megaterium were analysed by starch-gel electrophoresis and several non-inducible megacins were produced in liquid medium and they seemed to be a heterogeneous group which may correspond to ‘megacin B’. Expand
