Mutagenesis analysis of the RBBP1 CD and trimethylated lysine interaction.
1H-15N HSQC spectra of RBBP1 CD mutants titrated with M3L are exhibited for Y583A (A) (the M3L:protein molar ratio is from 0:1 to 15:1), Y592A (the M3L:protein molar ratio is from 0:1 to 15:1) (B), Y612A (the M3L:protein molar ratio is from 0 to 15:1) (C), W615A (the M3L:protein molar ratio is from 0 to 12:1) (D), and Y619A (the M3L:protein molar ratio is from 0 to 18:1) (E). F, KD values for binding of Y583A (upper panel) and Y592A (lower panel) to M3L.
