Biochemical characterization of type I-E anti-CRISPR proteins, AcrIE2 and AcrIE4

Applied Biological Chemistry

Table 1 Data collection, phasing, and refinement statistics of AcrIE2

^aValues in parentheses are for the highest-resolution shell
^b\({\text{R}}_{{{\text{merge}}}} ~ = \Sigma _{{\text{h}}} \Sigma \left| {{\text{I}}_{{\text{i}}} \left( {\text{h}} \right) - < {\text{I}}\left( {\text{h}} \right) > } \right|/\Sigma _{{\text{h}}} \Sigma _{{\text{i}}} {\text{I}}_{{\text{i}}} \left( {\text{h}} \right),\) where I_i(h) is the intensity of an individual measurement of the reflection and < I(h) > is the mean intensity of the reflection.
^c\({\text{R}}_{{{\text{cryst}}}} = \Sigma _{{\text{h}}} \left| {\left| {{\text{F}}_{{{\text{obs}}}} } \right| - \left| {{\text{F}}_{{{\text{calc}}}} } \right|} \right|/\Sigma _{{\text{h}}} \left| {{\text{F}}_{{{\text{obs}}}} } \right|,\) where F_obs and F_calc are the observed and calculated structure factor amplitudes, respectively
^dR_free was calculated as R_cryst using ~ 5% of the randomly selected unique reflections that were omitted from structure refinement
