From: CrfP, a fratricide protein, contributes to natural transformation in Streptococcus suis
Spectrophotometric lysis assays of CrfP. The activity of CrfP was measured by determining the decrease in the OD600 within 1 h. CrfP showed strong lytic activity against S. suis, including different serotypes but exhibited no lytic activity against E. coli or other Streptococcus species.
