Figure 6. In vitro repair of the isoaspartyl sites in aged recombinant CKB.

Figure 6

Aged recombinant human CKB was subjected to in vitro repair as described under “Materials and Methods” in the presence of PIMT and unlabeled AdoMet. CKB activity (right axis) before aging, after aging and after repair was determined and isoAsp content (left axis) was measured by a methanol diffusion assay. Each assay was performed in triplicate with error bars representing standard deviation.
