Figure 1. SsoCas6 cleaves a CRISPR RNA repeat.

Figure 1

(A) Representative time course of RNA cleavage by SsoCas6 at 60°C under single-turnover conditions, analysed by gel electrophoresis and phosphorimaging. Labels ‘s’ and ‘p’ indicate substrates and products respectively. The control reaction ‘c’ was carried out in the absence of SsoCas6 for 25 min. (B) Single-turnover kinetic rates for cleavage of a CRISPR repeat RNA by SsoCas6 as a function of reaction temperature. The sequence of the RNA oligonucleotide substrate is shown at the top with the cleavage position indicated with an arrow. Each rate was calculated from at least six data points as described in the Experimental section, with means±S.E.M. calculated from curve fitting shown.
