  • Bacillus anthracis (Sterne 34F2)
    Bacillus cereus ATCC 4342
    Bacillus megaterium WH320
    Bacillus subtilis 168
    Escherichia coli CFT073
 Efficient lytic activity against B. cereus, (efficacy compared to that reported for PlyG on B. anthracis); relatively high lytic activity against B. megaterium and low but detectable lytic activity was established on B. subtilis and B. anthracis. Other Issues
Lytic activity of C' truncated form of the lysin was found to be more active then its full-lenght form, most due to some inhibitory effects of the C-terminal domain on the N-terminal enzymatic domain.		 16103125
