From: Rice SUV3 is a bidirectional helicase that binds both DNA and RNA
RNA helicase activity of OsSUV3 protein. (A) Concentration dependence of RNA helicase activity. Lanes 1-6 show the activity with different concentrations (30-300 nM) of purified OsSUV3. (B) Time dependence of RNA helicase activity. Lanes 1-6 show the activity at different time points with 200 nM of purified OsSUV3. In A and B, lane C is the reaction without enzyme and lane B is the heat-denatured substrate.
