Heat inactivation: 65 °C for 15 minutes.
Application
SmaI is a restriction endonuclease used to cut DNA at the recognition sequence 5′-CCC/GGG-3′, generating DNA fragments with blunt termini.
Other Notes
Supplied with 10x Restriction Enzyme Buffer SA (B7531).
Comment: Half-life of Sma I at 37 °C is approximately 15 minutes.
Linkage
Isoschizomer: Xma I. Unlike Xma I, Sma I produces blunt-ended fragments.
Unit Definition
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.
Physical form

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

The properties and sources of all known class-I, class-II and class-III restriction endonucleases (ENases) and DNA modification methyltransferases (MTases) are listed and newly subclassified according to their sequence specificity. In addition, the enzymes are distinguished in a novel manner according
