应用
SmaI is a restriction endonuclease used to cut DNA at the recognition sequence 5′-CCC/GGG-3′, generating DNA fragments with blunt termini.
其他说明
Supplied with 10x Restriction Enzyme Buffer SA (B7531).
Comment: Half-life of Sma I at 37 °C is approximately 15 minutes.
联系
Isoschizomer: Xma I. Unlike Xma I, Sma I produces blunt-ended fragments.
单位定义
One unit is the enzyme activity that completely cleaves 1 mg of λDNA in 1 hr. at 25 °C in a total volume of 25 ml of 1x digestion buffer SA forrestriction enzymes.

The newly described Streptococcus pneumoniae serotype 6C accounted for 2.3% (16/709) of meningitis cases and 3.2% (3/95) of nasopharyngeal isolates from healthy individuals in Brazil. The strains were multidrug resistant (18.8%) and genetically diverse. Despite low serotype 6C prevalence, continuous
