Data Collection and Refinement Statistics for apo- TbPRMT6 and TbPRMT6-KI-SAH.

AValues in parentheses are for the highest resolution shell. BRmerge = Σh Σl |Ihl- |/ Σh Σl , where Ihl is the lth observation of reflection h and is the weighted average intensity for all observations l of reflection h. CRwork factor = Σh||Fobs(h) |- |Fcal(h) ||/Σh|Fobs(h) |, where Fobs(h) and Fcal(h) are the observed and calculated structure factors for reflection h respectively. DRfree factor was calculated same as Rwork factor using the 5% the reflections which were selected randomly and omitted from refinement.
