Table 5 Alkaline phosphatase (PhoA) activity under conditions of AICAR overproduction

From: Specific features of l-histidine production by Escherichia coli concerned with feedback control of AICAR formation and inorganic phosphate/metal transport

Strain AICAr, mg/L PhoA activity, µmol/min/mg
MG1655 (wild-type) < 0.1 410 ± 7
MG1655ΔpurR::CmR ΔpurH::KmR 7.6 261 ± 1
  1. PhoA enzymatic activity was analyzed 2 h after Pi exhaustion. Average data of PhoA activity from 3 independent experiments are represented
