To determined the phosphorylation sites of MvaU purified from MPAO1, PAO1, PAO1/pHERD20T-fpkA, PAO1/pHERD20T-fpkB, PAO1/pHERD20T-fpkA-pfkB and PAO1/pHERD20T-fpkA-pfkB-pfpC
To determined the effects of KK and KKP on the phosphorylation levels of proteins in PAO1, we overexpressed KK and KKP separately in PAO1 cells via pHERD20T based plasmids.
