Activity of AS-MPKs and Inhibition by NA-PP1. a Activity assay of wild-type and AS variants of MPK3/4/6 with MBP as substrate and [γ-32P] ATP as cofactor. b Same as in (A) but with ATPγS as cofactor in the substrate labeling reaction. c Same as in (B) but with Bn-ATPγS as cofactor. d Activity assay of AS-MPK3/4/6 with MBP as substrate and Bn-ATPγS as cofactor in the presence (+) or absence (-) of NA-PP1
