Targeted Amino-Terminal Acetylation of Recombinant Proteins in E. coli
Figure 3
Electron-spray mass-spectroscopy spectra for S. pombe Cdc8.
Cdc8 was purified from E. coli BL21-pNatB cells. The un-deconvolved mass charge envelope spectra show the purity of the protein. Deconvolution of this data indicates that all of the Cdc8 purified from BL21-pNatB cells is acetylated.
