Comments
|
Restriction digests of the clone give the following sizes (kb): EcoRI--5.9; BamHI--5.9; BglI/BglII--3.5, 2.4. The Bacillus subtilis promoter vegII initiates transcription in both B. subtilis and E. coli. Structural stability of the plasmid in B. subtilis can be affected by high levels of protein production. Under these conditions, cell growth and stability may be improved by reducing the antibiotic concentration in the media. May not be suitable for cloning very strong expression signals. Neo confers resistance to neomycin and kanamycin and ble confers resistance to bleomycin and phleomycin.
