Table 2 Data collection and refinement statistics for NCP assembled with H2A and either the same blunt-end 145 bp DNA fragment (NCP145) used for the H2A.X structure or the same sticky-end 147 bp DNA fragment (NCP147s) used for the γH2A.X structure.
From: PARP1 exhibits enhanced association and catalytic efficiency with γH2A.X-nucleosome
