Analysis of the binding affinity of WT SET7/9 and its catalytic mutants for unmodified and methylated TAF10 peptides

SET7/9 TAF10 peptide KDa
μm
WT K189 4.9 ± 0.20
WT K189me1 4.0 ± 0.36
Y305F K189 1.3 ± 0.10
Y305F K189me1 0.62 ± 0.065
Y305Fb K189me2 >70
Y245A K189 4.0 ± 0.25
Y245A K189me1 3.3 ± 0.10
Y245A K189me2 5.8 ± 0.22
Y245A K189me3 11 ± 0.28

a Curve fitting errors were calculated from the binding isotherms.

b An estimate of the affinity is reported due to weak peptide binding.
