FIGURE 4:
Catalysis and a C-terminal tail are required for normal Venus-Ppk1 localization. (A) Representative micrographs of venus-ppk1(H434A)++ expressed in the WT or ∆ppk1 background. For merged images in A and C, Venus is depicted in the red channel and DAPI (polyP) in the green channel. (B) Positions of Venus-Ppk1 or Venus-Ppk1(H434A) expressed from the native locus in populations of cells 120 min postsynchrony. For A and B, N = 299 cells with detected foci. (C) Representative micrographs of venus-ppk1(∆CT16)++ expressed in the WT or ∆ppk1 background. (D) Positions of Venus-Ppk1(∆CT16) in populations of cells grown in M2G. Cells were imaged at 120 min postsynchrony. For C and D, N = 352 cells with detected foci.
