Fig. 3: Ring nuclease activity of Crn4b and Csm6-2.
From: Structure and mechanism of the broad spectrum CRISPR-associated ring nuclease Crn4
a HPLC analysis of cleavage products of cA3, cA4 and cA6 incubated with Crn4b. Controls are as for Fig. 2a. b A. procaprae Csm6-2 possesses ring nuclease activity against cA6, but not cA3 or cA4. Source data are provided as a Source Data file.
