Table 2 Alkaline phosphatase activity within samples

From: The quantitative proteomic response of Synechocystis sp. PCC6803 to phosphate acclimation

Phosphate level Phosphate concentration (mg/L) APA (nmoles of Pi released per min per mg of protein) PhoA relative abundance PhoA standard deviation
100% 40 0 na na
3% 1.2 41.3 2.72 0.09
0.3% 0.12 60.7 3.74 0.28
  1. The phosphate concentration in the samples was determined using the acid molybdate method [37], and p-nitrophenylphosphate as substrate. Only alkaline phosphatase activity was detected.
