| Abstract: | SslI, a type II restriction endonuclease, was purified from Streptococcus salivarius subsp. thermophilus strain BSN 45. SslI is an isoschizomer of BstNI. SslI activity was maximum at pH 8.8, 0 to 50 mM NaCl, 2 to 8 mM Mg2+, and 42 degrees C. Activity against phage DNA in vitro was demonstrated. |
