LraI from Lactococcus raffinolactis BGTRK10-1, an Isoschizomer of EcoRI, Exhibits Ion Concentration-Dependent Specific Star Activity

Figure 4

Determination of influence of ionic strength in different reaction buffers on the LraI restriction enzyme activity. Commercial EcoRI restriction enzyme was used in control reactions. L: ladder (GeneRuler DNA Ladder Mix, Thermo Fisher Scientific). Black arrows present fragment obtained by LraI activity; white arrows present undigested plasmid DNA in EcoRI (Thermo Fisher Scientific) digestion.
