Signal transduction protein PII phosphatase PphA is required for light-dependent control of nitrate utilization in synechocystis sp. strain PCC 6803.

Journal of bacteriology - 1 Oct 2005

Kloft Nicole, Forchhammer Karl

Abstract excerpt

Signal transduction protein P(II) is dephosphorylated in Synechocystis sp. strain PCC 6803 by protein phosphatase PphA. To determine the impact of PphA-mediated P(II) dephosphorylation on physiology, the phenotype of a PphA-deficient mutant was analyzed. Mutants lacking either PphA or P(II) were impaired in efficient utilization of nitrate as the nitrogen source. Under conditions of limiting photosystem I...
