Protein phosphatase PphA from Synechocystis sp. PCC 6803: the physiological framework of PII-P dephosphorylation.

Abstract excerpt

The phosphorylated signal transduction protein P(II) (P(II)-P) in the cyanobacterium Synechocystis sp. strain PCC 6803 is dephosphorylated by PphA, a protein phosphatase of the 2C family (PP2C). In this study, the physiological conditions of P(II)-P dephosphorylation were investigated with respect to the in vivo specificity of P(II)-P towards PphA and the cellular abundance of PphA in cells growing under...
