Concurrent transcriptional activation of ppa and ppx genes by phosphate deprivation in the cyanobacterium Synechocystis sp. strain PCC 6803.

Biochemical and biophysical research communications - 14 Mar 2003

Abstract excerpt

The cyanobacterium Synechocystis sp. strain PCC 6803 possesses two genes, named ppa and ppx, which, respectively, encode proteins involved in the hydrolysis of inorganic phosphate polymers, namely, inorganic pyrophosphatase (PPA, EC 3.6.1.1), an essential enzyme that hydrolyzes pyrophosphate, and exopolyphosphatase (PPX, EC 3.6.1.11), a processive enzyme that releases the terminal orthophosphate group from linear...
